Question

A load of 1 kW takes a current of 5 A from a 230 V supply. Calculate the power factor.

Answer 1

Power factor = 0.87 (Approx)

Step-by-step explanation:

Given:

Load = 1 Kw = 1000 watt

Current (I) = 5 A

Supply (V) = 230 V

Find:

Power factor.

Computation:

Power factor = watts / (V)(I)

Power factor = 1,000 / (230)(5)

Power factor = 1,000 / (1,150)

Power factor = 0.8695

Power factor = 0.87 (Approx)
