An electric motor takes 5 A from a 220 V line. Determine the power of the motor and the energy consumed in 2 h.

The equation may be used to compute the motor’s power.

VI = P

We obtain by substituting the numbers in the preceding equation.

220 V x 5 A = 1100 W

The equation may be used to calculate the motor’s energy consumption.

E = PT

We obtain by substituting the numbers in the preceding equation.

7200 = J P = 1100 W

The motor has a power of 1100 W, and it consumes J of energy.
