Circuit solver (Kirchhoff's laws)
Describe a circuit part by part and get the current through and potential difference across every part, worked out with Kirchhoff’s laws - cells with internal resistance, resistors, capacitors, galvanometers and Wheatstone bridges - and the equivalent resistance between any two points.
