Ohm’s Law

E = I X R

Where: E = Voltage (Volts)

I = Current (Amps or Amperes)

R = Resistance (Ohms or W

W)

Formula Variations:

I =E / R

R = E / I

Power Formula

P = I X E

Where: P = Power (Watts)

I = Current (Amps or Amperes)

E = Voltage (Volts)

Formula Variations:

I = P / E

E = P / I

P = I2 X R

P = E2 / R

Apply the numbers from the above formulas to the Power wire calculation to determine the minimum gauge wire to properly

supply the amplifier with current.
