Question: If the peak current in an AC circuit is 5 A, what is the average current over one complete cycle?

Options:

Correct Answer: 2.5 A

Solution:

The average current over one complete cycle is I_avg = I_peak/√2 = 5/√2 = 2.5 A.

If the peak current in an AC circuit is 5 A, what is the average current over one complete cycle?

If the peak current in an AC circuit is 5 A, what is the average current over one complete cycle?

Step 1: Understand that in an AC circuit, the current varies over time and has a peak value, which is the maximum current reached.
Step 2: The peak current given in the question is 5 A.
Step 3: To find the average current over one complete cycle, we use the formula: I_avg = I_peak / √2.
Step 4: Substitute the peak current value into the formula: I_avg = 5 A / √2.
Step 5: Calculate √2, which is approximately 1.414.
Step 6: Divide 5 A by 1.414 to find the average current: I_avg ≈ 5 A / 1.414 ≈ 3.54 A.
Step 7: Therefore, the average current over one complete cycle is approximately 3.54 A.
