Color Coding Of a Resistor

Normally 4-Band Resistors are used.So I Will Explain That. First Select First Color ex-Brown-1 Then Select Next Color ex-Black-0 Then Select Next Color That Is The Multiplier ex-Red-2 So The Value Of The Resistance Is 1000,ohm. If The Multiplier Is 2 Add Two Zeros After The First Two Numbers.
If The Third Color Is Gold Add One Dot Between The Two Numbers ex-2.2,ohm

Resistor

A linear resistor is a two-terminal, linear, passive electronic component that implements electrical resistance as a circuit element. The current through a resistor is in direct proportion to the voltage across the resistor's terminals. Thus, the ratio of the voltage applied across a resistor's terminals to the intensity of current through the resistor is called resistance. This relation is represented by

I=V/R

I-Current Through The Resistor
V-Voltage Through The Resistor
R-Resistance Of The Resistor
