The Equations that are used for Electricity.

Click on an equation below for more information.

The two most important equations in electricity are given below.

P = V x I power = voltage x current.

V = I x R voltage = current x resistance.

Other equations that you should know
include

P = E ÷ t power = energy ÷ time.

Q = I x t charge = current x time.

E = V x I x t energy = voltage x current x time.

E = V x Q energy = voltage x charge.

W
= V x Q
work
= voltage x charge.

The
equations work whether the
electricity is

direct current
or alternating
current. See calculations.
