1. Give the significance of using the resistor in an electrical circuit.
2. What is more efficient to use: a resistor with high tolerance or a resistor with low tolerance? WHY?
A resistor limits the amount of current that can flow through a circuit based the resistance of the resistor.
A resistor is a passive two-terminal
electrical component that implements electrical resistance as a circuit
element. Resistors act to reduce current flow, and, at the same time,
act to lower voltage levels within circuits. In electronic circuits
resistors are used to limit current flow, to adjust signal levels, bias
active elements, terminate transmission lines among other uses.
High-power resistors that can dissipate many watts of electrical power
as heat may be used as part of motor controls, in power distribution
systems, or as test loads for generators. Resistors may have fixed
resistances that only change a little with temperature, time or
operating voltage. Variable resistors can be used to adjust circuit
elements (such as a volume control or a lamp dimmer), or as sensing
devices for heat, light, humidity, force, or chemical activity. EHEM!
WHAHAHAH.
If we are going to talk about Resistors, it
is essentially connected with circuits. Resistor, is any device of
material that limits the flow of current when emf is applied. It is a
device that is usually made of wire or carbon
which presents a resistance to current flow. If we are talking about high resistant resistor, it will only allow less current to pass through otherwise for a low resistant resistor that allow more current to pass through. But for me it I prefer using a low resistant capacitor to prevent overheating of the circuit because high resistance means electron cannot freely move that is why heat is being produced due to friction.

ah! Another Answer!!
Simple! To resist or control the current flow.
2)Resistors with power dissipation below 5 watt most commonly used types and the Resistor with power dissipation above 5 watt are rarely use.
Sorry.. The answer is the Low tolerance resistor is efficient to use.
The significance of using a resistor is that
it reduces or limits the flow of the current in an electric circuit.
And for the second question, siguro idedepende ko na lang to sa kung
saan natin ia-apply yung resistor, kasi if we're talking about circuits,
literally ang most efficient resistor to use is the resistor with low
resistance. Di ako sure sa mga sinabi ko XD
In the early times, scientists defined the
electricity as some type of "invisible fluid" that could flow through
any material easily. In a way they were correct. Furthermore, the
movement of electrons cannot be seen by the naked eye even though you
used a microscope.For an electron, the journey from terminal to terminal
is not a direct route.The electrons encounter resistance - a hindrance
to their movement.
Resistors restrict or limit the flow of current in a circuit. Their function is in their name,to resist current flow.Resistors determine the flow of current in an electrical circuit. Where there is high resistance in a circuit the flow of current is small, where the resistance is low the flow of current is large. Resistance, voltage and current are connected in an electrical circuit by Ohm’s Law.The ability of a material or component to resist current flow is measured in ohms.
I think the more efficient to use is the resistor with low tolerance because its more stable than the resistors with high tolerance. To sum it up, the larger the resistor tolerance, the more it may vary, either up or down, from its nominal value. The smaller the resistor tolerance, the less it varies from its nominal value and, thus, the more stable it is.

Ang
resistor, panagwil, o panakwil ay isang elektronikong sangkap na
hinihigpitan ang daloy ng kuryente sa isang elektrikal o elektronikong
sirkito. Ginagamit ito upang pigilin ang boltahe. Ginagamit din ito
upang ipagsanggalan ang sensitibong mga sangkap sa
pagsabog/pamumulaklak. Kapag mas mataas ang pagpigil, mas magiging
mababa ang daloy.
Ang Resistors ay normal na dinisenyo at pinapatakbo nang sa gayon, ay may iba't ibang antas ng sa kasalukuyan, ay may mga pagkakaiba-iba ng kanilang mga halaga ng paglaban. Makikita ang mga ito sa ilang karaniwang mga form wirewound resistors na nabuo mula sa windings ng fine wire; film resistors, at karaniwang matatagpuan sa mga consumer ng electronic devices, ginagamit ang mga haba ng carbon o metal film ideposito sa isang resistive base
at carbon-komposisyon resistors ay gumamit ng isang bonded mass ng carbon powder na may phenolic binder. Ang ilang mga resistors ay ginagawa upang ang kanilang mga halaga ay maaaring nababagay o sa ingles ay naaadjust.Mas mainam gamitin ang resistor na may mababang tolerance upang ang boltahe sa isang sirkito ay di gaanong kataas at kababa ang pagbabago ng boltahe sa isang sirkito.

1. Because we already have known that
Resistor resist the flow of electrons, it means that it can control the
voltage that is needed. It is important because if there is no resistor
in a circuit or electronic devices there will be a short circuit
happens.
2. A resistor with a low tolerance is more efficient rather that a resistor with high tolerance because, it can safely pass through a current.

1. A resistor limits the amount of
electrical current that passes through the circuit.it means it regulates
the current to prevent overflowing of electricity.
2)Resistors with power dissipation below 5 watt most commonly used types and the Resistor with power dissipation above 5 watt are rarely use.

2. Well, it's great to used the resistor with the Low Tolerance because the value itself are more accurate than the other.

To resist or control the current flow. If a
pure conductor (ie, wire) instead of a resistor is used, the path is
said to be short circuited and, in theory - but not usually in practice -
an infinite current would flow through it if the source was really able
to deliver such a current. But, if there is some resistance in its
path, the current taken from the source will always be limited to the
potential difference produced by the source (measured in volts) divided
by the resistance of the path (measured in ohms). I = E/R (Where I is
current, E is volts and R is resistance) Another use of a resistor is
whenever you need to produce a voltage drop in a circuit

The purpose of any electrical circuit, electronic or otherwise, is to power some kind of load which itself provides an amount of resistance and is thus some form of resistor.....
☺ 2.:) low tolerance mean it allow easy passage to current... I think the more resistance'" the harder it is to push through" would have less current, because its not as easy for the electrons to flow through. hahaha
☺ I think I'm finish so their for I conclude that resistor that low tolerance is more efficient to use than high tolerance..

FOLLOW UP QUESTION, pwede kayong mamili kung ano gusto niyo sagutan. Yung naunang mga tanong o ito.
Tanong:
Sa pagsusukat ng resistance ng resistor, anong mas gusto niyong gamitin. Ang mga color codes at color bands around the body of a resistor? o ang paggamit ng multi-tester?

hmmm. Para saken wala. 
For emergency use kapag color yung pagbabasehan. Pag tester, mas malalaman mo ung exact resistance.

multitester, mas madali kasi itong gamitin at mas mapapabilis pa yung trabaho mo sa pagsusukat ^_^

Pag multi tester kase ang ginamit maaari mu
din masukat yung resistance ng kamay mo pero mas maganda kung multi
tester kase makukuha mu yung exact value ng resistor ^^
Para sakin unang una dapat mong icheck ang
color codes ng resistor na binili mo para malaman mo kung tama ang
binigay sayo.Pero kaylangan mo paring icheck ang value nito sa
multimeter para masigurado na good o pasok pa ang value nito sa
tolerance range ng resistor

nice :) very informative and malalaman din yung bawat opinion ng mga tao . makakatulong to :)
ReplyDeleteA resistance opposes the flow of electric current. So, in terms of conductivity, obviously a low resistance is better. Besides, heat is developed as a result of resistance, which is not desirable in some appliances. So resistors are also used to prevent overheating of appliances.
ReplyDeleteIn terms of efficiency with regards to resistor's tolerance, I think resistors with high tolerance would be more efficient. Because with high tolerance the range of the resistance would be greater, so it can easily adapt into the minor changes in the current flow.
Good thing that you see my blog and adds your opinion about this. Thank you Marquina. :) Pls do participate well in my final demo bukas.

DeleteA resistor limits the amount of electrical current that passes through the circuit. Think of kinking a garden hose. The kink "resists" the flow of water. Similarly, a resistor "resists" the current flow and thus lowers the voltage to the following parts of the circuit which that current has to flow through. Another answer Simple...To resist or control the current flow. If a pure conductor (ie, wire) instead of a resistor is used, the path is said to be short circuited and, in theory - but not usually in practice - an infinite current would flow through it if the source was really able to deliver such a current. But, if there is some resistance in its path, the current taken from the source will always be limited to the potential difference produced by the source (measured in volts) divided by the resistance of the path (measured in ohms). I = E/R (Where I is current, E is volts and R is resistance) Another use of a resistor is whenever you need to produce a voltage drop in a circuit. This drop can can then be utilized for some other purpose, noting the voltage will differ depending on the load. If the load varies in resistance, so will the voltage drop. When no resistors are met by the current, the voltage which is actually the amount of work done in moving the charge will tend to zero. This means that the current flows without any resistance and is said to be a dead short to the source.
