How much power does a 100W guitar amp use?
If you use a 100W amp at 40% power (which is quite generous for a practice amp), that would mean a 40W load on your mains. If you then use it for two hours every day, you would get 40W x 2hrs x 30 days = 2.400Whr = 2,4kWh. Depending on where you live, you will have an estimated price of each kWh.
How do I convert watts into amps?
Amps calculation with line to line voltage
- I(A) = P(W) / (√3 × PF × VL-L(V) ) So amps are equal to watts divided by square root of 3 times power factor times volts.
- amps = watts / (√3 × PF × volts) or.
- A = W / (√3 × PF × V) Example.
- I = 330W / (√3 × 0.8 × 110V) = 2.165A. Amps calculation with line to neutral voltage.

How many Amps does a 1200 watt car amp draw?
1200 watts is 100 amperes at 12 volts, and 10 amperes at 120 volts. (power = volts x amperes) So we also need to know that. It should give you that information on the back of the amp. 10 amps would be a good guess but that also depends on the class of the amp.
