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.
= V x Q
= voltage x charge.
equations work whether the
direct current or alternating current. See calculations.
