Solution

The correct option is C Maximum positive amplitude is more than maximum negative amplitude
Alternating currents are:
1. Periodic with a constant time period.
2. Have average value 0.
3. Magnitude of positive part of current is same as magnitude of negative part of current. Hence option C is correct.
