A problem that my professor gave me.

A 5kw 240v motor has current measured at 14Amps. The meter shows that the motor is drawing 2kw. Draw vectors of voltage and current! And calculate power factor... I'm lost any help would be appreciated

p.f. = watts / volt amperes

so 2000 / 240x14 = p.f.

that may get you started. Was this not given in your class material or in lecture?
