A generator supplies 150VAC phase and load is 10 Ohms per phase. What is the phase current ?
- 25.5 A.
- 1.5 A.
- 15 A.
Explanation
Phase current is found from Ohm's law: I = V / R = 150V / 10 ohms = 15A per phase. The 25.5A and 1.5A options do not result from any correct combination of these values, so the phase current is 15A.
watzz asking:
How to work out please

Hey.
I = V/R = 150/10 = 15A
I = V/R = 150/10 = 15A
