Question

How much power is being used in a circuit when the applied voltage is 12 volts DC and the current is 2.5 amperes?

a) 30 watts
b) 24 watts
c) 10 watts
d) 6 watts

Answer 1

The power being used in the circuit is 30 watts.

Step-by-step explanation:

To find the power being used in a circuit, we can use the formula:

Power = Voltage x Current

Given that the applied voltage is 12 volts DC and the current is 2.5 amperes, we can calculate the power as follows:

Power = 12 V x 2.5 A = 30 watts

Therefore, option a) 30 watts is the correct answer.
