In electric motor delivers 23 hp of mechanical power into a load it runs on single phase 440 VAC and is 83 percent efficient its running power is .77 and the starting current is 70 percent higher than its running current

A) find its running current

B)starting current

C)suitable circuit breaker value

D)phase angle between current and voltage in motor
