Examples for

Capacitors

Capacitors are circuit elements that store electrical energy in an electric field. Use Wolfram|Alpha to compute the capacitance of a parallel plate capacitor, capacitors in parallel and series, and a variety of other physical systems. Calculate the energy stored in a capacitor or its capacitive reactance.
Capacitors
