# 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.

### Circuits

Calculate the behaviors of circuits and circuit elements, such as the effects of alternating current, voltage levels under parallel and series configurations and the power used by a circuit component.

#### Do computations with Joule's law:

Resistors

Compute the resistance of resistors in parallel and series. Translate resistor color codes to and from resistance values.
