Title: Module 8: Power Calculations
Course: Basic Electrical Theory and Wiring (Sandbox) > Section: Module 8: Power

Calculating Power

 | Formulas |
Calculating Power (AC)

\(P=V\times I\times pf\)

Calculating Power (DC)

\(P=V\times I\)

Alternative Equations

 | Formulas |
\(P\:=\:R\times I^2\)

\(P=\frac{V^2}{R}\)

Variables

- V = Voltage in volts (V) (This can also be displayed as E for electromotive force)
- I = Current in amps (A)
- R = Resistance in ohm's (Ω)
- P = Power in watts (W)
- pf = Power Factor
