Amplifier power consumption

Amplifier power consumption

The average electrical consumption per hour of an amplifier is 100 to 200 watts. To put that into perspective, they use a similar amount of electricity as a refrigerator, slightly more than lights on the ceiling, and ten times less than a standard air conditioner.

How do I calculate power consumption of an amp?

The key formula to remember is this:

  1. Watts = Amps x Volts.
  2. Volts = Watts / Amps.
  3. Amps = Watts / Volts. . So let's look at some everyday examples:

How many watts does an amp draw?

How many watts make an amp? At 120V, 120 watts make 1 amp. That means that 1 amp = 120 watts.
