Series and parallel resistor circuits are a part of a standard science study. Problems usually require you to calculate the total resistance of a circuit or ask for an equivalent resistance using the best combination of resistors.

Our Parallell Resistor Calculator helps you find the total equivalent resistance in a parallel circuit or series of resistors. Simply enter the resistances separated by commas to generate a result.

For those just learning, we have prepared the ultimate Q&A for our parallel resistance calculator. We cover resistor basics, calculating resistance and more.
