How many watts are in 3 amps?

Answer 1

The conversion of watts to amps at a fixed voltage is governed by the equation

Amps = Watts/Volts

for example 12 watts/12 volts = 1 amp

for a US example, a food mixer with a 400 watt motor on a 120 volt supply 400/120 = 3.33amps, fit a 5amp fuse

Answer 2

To calculate watts, you need to know the voltage. However, if we assume a standard household voltage of 120 volts, then 3 amps would be equivalent to 360 watts (3 amps * 120 volts = 360 watts).

Answer 3

Watts (power) is calculated by multiplying volts and amps. 18 amps multiplied by 10 volts would be 180 watts.

Answer 4

P=VI so 18.5*3.5=64.75W
