Question: What is the root mean square (RMS) value of an alternating current (AC) if its peak value is 10 A?

Options:

  1. 5 A
  2. 7.07 A
  3. 10 A
  4. 14.14 A

Correct Answer: 7.07 A

Solution: 

The RMS value of an AC is given by I_rms = I_peak / √2. Therefore, I_rms = 10 A / √2 = 7.07 A.

What is the root mean square (RMS) value of an alternating current (AC) if its peak value is 10 A?
Correct Answer: 7.07 A
  • Step 1: Understand that the peak value of the AC current is given as 10 A.
  • Step 2: Know the formula to find the RMS value, which is I_rms = I_peak / √2.
  • Step 3: Substitute the peak value into the formula: I_rms = 10 A / √2.
  • Step 4: Calculate √2, which is approximately 1.414.
  • Step 5: Divide 10 A by 1.414 to find the RMS value: I_rms = 10 A / 1.414.
  • Step 6: Perform the division to get I_rms ≈ 7.07 A.
