Capacitors in series

This capacitors in series calculator finds the equivalent capacitance of up to 10 capacitors in series.

Parallel resistor

When two (or more) resistances are in parellel, then the resitence provided by the two together is given by reciprocal addition, i.e. 1/(total resistence) = (1/resistance1) + (1/resistance2).
