Electric energy formulas

Electrical energy is electrical power measured over a period of time. It can be specified in watts/second or kilowatts/hour.

Electrical energy
\(\displaystyle energy= power · time\)
\(\displaystyle E=P·t\)	\(\displaystyle E=U·I·t\)
Electrical power
\(\displaystyle P=\frac{E}{t}\)	\(\displaystyle P=U·I\)
Time period
\(\displaystyle t=\frac{E}{P}\)
