# Electric Circuits

Electric circuits consist of closed loops of electric current. These devices underpin all modern electronics. Use Wolfram|Alpha to compute properties of different circuit elements and their combinations, including diodes, filters and other circuits. Get information on resistors, inductors and capacitors. Examine the relationship between resistance and current with Ohm's law.
