There is a relationship between electrical parameters: voltage (potential), amperage (intensity), resistivity (impedance), and power.
This equation will calculate Voltage (V) using the Power (P) and the Resistance (R)
Ohm's Law provides the following equation:
`V = I * R`
and the power law equation provides the formula:
`P=I*V`
where:
P = power
I = current (I for international ampere)
R = resistance
V = Voltage
From these we can see that:
`V = sqrt(P * R)`
`V= P/I`
`V=I * R`
