Which of the following household electrical appliances has the greatest rate of energy

consumption?

ITEM VOLTAGE CURRENT
A. Video Camera 6.0 V 1.6 A
B. Radio 4.5 V 0. 45 A
C. Cassette Recorder 6.0 V 2.2 A
D. Ghetto Blaster 12 V 1. 4 A
.

D. P = 12 * 1.4 = 16.8W. = Greatest energy consumption.

To determine which household electrical appliance has the greatest rate of energy consumption, we need to calculate the power for each appliance using the formula: Power (P) = Voltage (V) * Current (I).

Let's calculate the power for each appliance:

A. Video Camera: P = 6.0 V * 1.6 A = 9.6 W
B. Radio: P = 4.5 V * 0.45 A = 2.025 W
C. Cassette Recorder: P = 6.0 V * 2.2 A = 13.2 W
D. Ghetto Blaster: P = 12 V * 1.4 A = 16.8 W

From the calculations, we can see that the Ghetto Blaster has the highest power consumption with 16.8 watts. Therefore, the Ghetto Blaster has the greatest rate of energy consumption among the given household electrical appliances.
