How Do You Calculate Amp Draw. It consists of 20 amps for 1 second followed. The current I in amps A is equal to the square root of the power P in watts W divided by the resistance R in ohms.
Thus the current in amps is equal to horsepower times 746 divided by the voltage times the efficiency η times the power factor. The current I in amps A is equal to the power P in watts W divided by the voltage V in volts V. AC three phase watts to amps.
For a single phase AC circuit the formula to convert kilowatts kW to amps is.
After the steps above the final formula for converting horsepower to amps is. DC watts to amps calculation formula. 20 x 20 mins 60 Mins 1hr AH. It draws just over 7 amps at 18 power 4 ohms pink noise signal at 120 volts.
