PARALLEL RESISTANCE CALCULATOR

Parallel Resistance Calculator – Find Equivalent Resistance (Req​) 

 Fast and accurate parallel resistor calculator. Calculate the total equivalent resistance for two or more resistors in parallel. Includes formula, examples, and circuit theory. Theory: When resistors are connected in parallel, the total resistance decreases because there are more paths for the current to flow. The formula for the equivalent resistance (Req​) of n resistors is:

For just two resistors, you can use the shortcut:
