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.

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.

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

Calculate properties of a diode based on current or voltage.

Compute electric current, voltage and resistance using Ohm's law.

Compute the capacitance of a parallel plate capacitor, capacitors in parallel and series and a variety of other physical systems.

Calculate properties of signal processing filters, such as transfer function, pole locations and Bode plots.

Compute inductance of various physical systems. Compute the energy storage and inductive reactance of inductors.
