Question: What is the power consumed by a 5 ohm resistor when a current of 2A flows through it?

Options:

Correct Answer: 20W

Solution:

Power P = I^2 * R = (2A)^2 * 5 ohms = 4 * 5 = 20W.

What is the power consumed by a 5 ohm resistor when a current of 2A flows through it?

Correct Answer: 20W

Step 1: Identify the values given in the problem. We have a resistor with a resistance of 5 ohms and a current of 2A flowing through it.
Step 2: Recall the formula for power (P) in an electrical circuit, which is P = I^2 * R, where I is the current and R is the resistance.
Step 3: Substitute the values into the formula. Here, I = 2A and R = 5 ohms.
Step 4: Calculate I^2. This means multiplying the current by itself: (2A) * (2A) = 4A^2.
Step 5: Now multiply the result from Step 4 by the resistance: 4A^2 * 5 ohms = 20W.
Step 6: The final answer is that the power consumed by the resistor is 20 watts.
