I=V/R, this is a most basic equation to use to understand what a resistor is and what it does, from the equation it can be seen that an increase of V, will result in an increase of I, also an increase of R will result in a decrease of I, because of that, resistors are used to reduce I so as to control the level of V in a circuit.

When they can use a resistor in a circuit?
When the circuit needs the electrical property of resistance, of course.
Can you use a 91ohm resistor in place of 100ohm resistor?
It depends on where you are going to use this resistor and what its application going to be. If the circuit you are using can tolerate this then you are fine.
Resistor and capacitor built circuit for alarm switch?
I wanna use resistor , capacitor and amplifier 7173 for switch alarm circuit. How can i choice resistor and capacitor value because i wanna use 24V DC.
What does a resistor do in an ampliflyer circuit?

How do you use resistor in a sentence?
I installed a resistor inline with my oil pressure sensor. The resistor in a circuit will usually disperse energy as heat.
How connect a variable resistor to circuit?

Why resistor should disconnected from the circuit when measured the value of resistor?
if not disconnected you will measure the resistance of the circuit in parallel with the resistor.
Where do you use the current limiting resistor?
in a flashing led circuit connected in series
What parts of a circuit acts as a resistor?
Any part of a circuit that has a voltage drop across it is a resistor.
A can be used to reduce the current in a circuit?
A resistor.
What does the variable resistor do in a circuit?
It is used to vary the voltage/current flow in a circuit.
What is the use of resistor in the circuit?
A resistor develops a voltage differential when current is passed through it. Ohm's law: Voltage is current times resistance.
