Ohms Law
A law that explains the relationship between voltage, current and resistance. The law states
that the electric current flowing through a conductor is equal to the voltage divided by the
resistance. The following equations further explain ohms law.
V = Volts
(electrical pressure)
A = Amps
(electrical flow/current)
O = Ohms
(resistance to electrical flow/current)
W = Watts
(rate or amount of electricity used)
Ohms Law applied to single phase power - each loop of a six wire element:
Ohms Law applied to three phase power - each wiring lead to a three wire element:
Service Note:
See Heating Element Ratings on page 23 to determine the voltage and KW
rating of a heating element.
V ÷ A = O
W ÷ V = A
V ÷ O = A
V x A = W
A x O = V
W ÷ A = V
0.577 x W ÷ V = A
V x A x 1.73 = W
