Parallel and Series Resistor Calculator

About:

The parallel resistor calculator calculates the total parallel resistance of a circuit.

Formula: RT = 1 / (1/R1 + 1/R2 + 1/R3 + etc..)

The series resistor calculator calculates the total series resistance of a circuit.

Formula: RT = R1 + R2 + R3 + etc..
