## 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

$$\displaystyle t=\frac{E}{P}$$
