# Joule's Law

`E = R * I^2 * t`

Joule's Law (also called Joule effect) calculator.

Joule's Law (also called Joule effect) calculator.

**Enter 'x' in the field to be calculated.**This tool is a Joule's Law calculator. This law expresses the relationship between heat dissipated in a conductor, the current flow, the resistance of the conductor, and time.

`H = R * I^2 * t`

H: heat dissipated in joule

R: resistance of the conductor in ohm

I: current in ampere

t: time for which the current flows in second
