Question

How much power is being used in a circuit when the applied voltage is 13.8 volts DC and the current is 10 amperes?

a) 1.38 watts
b) 13.8 watts
c) 138 watts
d) 1380 watts

Answer 1

The power in the circuit is 138 watts.

Step-by-step explanation:

The power in a circuit can be calculated using the formula:

Power (P) = Voltage (V) * Current (I)

So, in this case, with an applied voltage of 13.8 volts and a current of 10 amperes, the power can be calculated as:

Power = 13.8 V * 10 A = 138 watts

Therefore, the correct answer is C) 138 watts.
