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
\(\displaystyle t=\frac{E}{P}\)
