## Resistors
### A resistor is a two-terminal electronic component that produces a voltage across its terminals that is proportional to the electric current. When a voltage (V ) is applied across the terminals of a resistor, a current (I) will flow through the resistor in direct proportion to that voltage. The reciprocal of the constant of proportionality is known as the resistance (R), with a given voltage (V), a larger value of (R) further "resists" the flow of current (I) as given by Ohm's Law. Resistors have no polarity, installation can be done in either direction.
## 4 Band Resistor
Combine the 1st color band and the 2nd color band then multiply by the 3rd band for the resistance value.
## 5 Band Resistor
Combine the 1st and the 2nd and 3rd color band then multiply by the 4th band for the resistance value.
## Resistor Color Chart
The chart will define each band and determine the resistance.
