Crown Audio Calculators: Ohm’s Law / Watt’s Law

A useful calculator for designing audio systems with Crown amplifiers.

By PSW Staff June 17, 2009

Ohm’s Law states the relationship between current, voltage and resistance. Watt’s Law states the relationships of power to current, voltage and resistance.

Enter any two known values and press “Calculate” to solve for the others. 

Fields should be reset to 0 before each new calculation.

Equations used to calculate the data:

V = IR
P = VI

I = current
P = power
R = resistance
V = voltage
