The peak value of alternating current is $5 \sqrt{2}$ ampere. The mean square value of current will be

5 A

2.5 A

$5 \sqrt{2}$ A

None of the above

Solution

5 A

Peak value of alternating current is known as "equivalent" or DC "equivalent" value of AC voltage or current. For sine wave, the RMS value is approximately 0.707 of it's peak value. The crest factor of an AC waveform is the ratio of its peak (crest) to its RMS value.

$Here : - I_{o} = 5 \sqrt{2} A Root mean square value of current I_{rms} = \frac{I_{o}}{\sqrt{2}} = \frac{5 \sqrt{2}}{\sqrt{2}} = 5 A$
