Resistors Are Used To Direct The Flow Of A Current To Certain Parts Of The Circuit. Resistors Also Are Used To Determine The Voltage Gain Of An Amplifier.
What is a resistor?

Symbol

Resistance Is The Resistor's Ability To Reduce The Current And Is Also Measured In The Units Of Ohms: Symbol, Ω.

Ohm's Law

Ohm's Law: I = V/R

I = Current Measured In Amps

V = Voltage Measured In Volts

R = Resistance Measured In Ohms

1st Band: Provides The First Digit Of The Code

2nd Band: Provides The Second Digit Of The Code

3rd Band: Is The Multiplier

4th Band: Indicates The Tolerance Value
