Explanation:

Electric power is the rate of transfer of electrical energy in a circuit. Power is the product of current and voltage expressed in wattage. The formula for power is given as:

Power = current × voltage.

Define the required wattage for a UPS to be used with the following systems:

(assuming that the systems are operating in the United States at a standard voltage of 120 volts at 60 Hz)

a) Monitor: 2 amps; CPU: 3 amps; printer: 3 amps

Power = (2 × 120) + (3 × 120) + (3 × 120) = 960 W

b. Monitor: 3 amps; CPU: 4 amps; : 3 amps

Power = (3 × 120) + (4 × 120) + (3 × 120) = 1200 W

c. Monitor: 3 amps; CPU: 4 amps; printer: 4 amps

Power = (3 × 120) + (4 × 120) + (4 × 120) = 1320 W
