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.
