Question: If a circuit has a total resistance of 12Ω and a voltage of 24V, what is the power consumed by the circuit?

Options:

Correct Answer: 48 W

Solution:

Power P = V²/R = 24² / 12 = 48 W.

If a circuit has a total resistance of 12Ω and a voltage of 24V, what is the power consumed by the circuit?

If a circuit has a total resistance of 12Ω and a voltage of 24V, what is the power consumed by the circuit?

Step 1: Identify the given values. We have a total resistance (R) of 12 ohms (Ω) and a voltage (V) of 24 volts (V).
Step 2: Use the formula for power (P) in a circuit, which is P = V² / R.
Step 3: Substitute the values into the formula. Replace V with 24 and R with 12: P = 24² / 12.
Step 4: Calculate 24 squared (24²). This equals 576.
Step 5: Divide 576 by 12 to find the power: 576 / 12 = 48.
Step 6: Conclude that the power consumed by the circuit is 48 watts (W).
