Question

Which requires the most electrical power during operation?(Note: 1 horsepower = 746 watts)

A. A 12-volt motor requiring 8 amperes.
B. Four 30-watt lamps in a 12-volt parallel circuit.
C. Two lights requiring 3 amperes each in a 24-volt parallel system.

Answer 1

Option C requires the most electrical power during operation with 144 watts.

Step-by-step explanation:

To determine which requires the most electrical power during operation, we need to calculate the power for each option.

A. The power of a 12-volt motor requiring 8 amperes can be calculated using the formula P = IV, where P is power, I is current, and V is voltage. So, P = 8A * 12V = 96 watts.

B. The total power of four 30-watt lamps in a 12-volt parallel circuit can be calculated by adding the power of each lamp, so 4 * 30 watts = 120 watts.

C. The power of two lights requiring 3 amperes each in a 24-volt parallel system can be calculated the same way, so 2 * 3A * 24V = 144 watts.

Therefore, option C requires the most electrical power during operation, with 144 watts.
