Question: What is the total power consumed in a circuit with a current of 5A and a total resistance of 4Ω?

Options:

Correct Answer: 40W

Solution:

Power (P) = I^2 * R = 5^2 * 4 = 25 * 4 = 100W.

What is the total power consumed in a circuit with a current of 5A and a total resistance of 4Ω?

Correct Answer: 100W

Step 1: Identify the formula for power in a circuit, which is P = I^2 * R.
Step 2: Substitute the given current (I) into the formula. Here, I = 5A.
Step 3: Calculate I^2, which is 5^2 = 25.
Step 4: Substitute the total resistance (R) into the formula. Here, R = 4Ω.
Step 5: Multiply the result from Step 3 by the resistance from Step 4. So, 25 * 4 = 100.
Step 6: The total power consumed in the circuit is 100W.
