Solved Examples for 18 kW to Amps for DC and AC Circuits
In the case of DC
A 120 V DC volts applied across a circuit consuming 18 kW of power will have how much current flowing across it.
Solution: Using formula
I = (kW * 1000)/E = 18 * 1000 / 120 = 150.
In case of Single Phase AC
Repeat the previous problem for single-phase AC circuit assuming power factor to be 0.8
I = (kW * 1000)/(E*PF) = (18 * 1000) / (120 * 0.8) = 187.5 A
In case of Three Phase AC
Repeat the problem for three-phase AC while assuming Power factor as 0.8
I = (kW * 1000) / (E*PF * 1.73) = (18 * 1000) / (120 * 0.8 * 1.73) = 108.38 A
