Equivalent Circuit Calculator

Diagram the parallel/series* circuit of resistors or capacitors below as a comma-separated list of numbers and arrays. Numbers (integer or decimal) represent resistance or capacitance values. Using nested arrays, you can indicate parallel branches.

Diagram Examples

Each example shows an image of a circuit segment (with resistors or capacitors), followed by the text ‘diagram’ you would use to represent it in the box above.

100, 200, 300

30, [[0.7], [4, 12.5], [10]]

[[3], [2], [1]]

10, [
