The r.m.s value of current in a 50 Hz A.C. circuit is 10 A. The average value of A.C. current over a cycle is
Options
- AZero
- B10 A
- C7.072 A
- D14.14 A
Correct answer
A. Zero
Step-by-step solution
The average value of a sinusoidal alternating current over a complete cycle is given by the integral of the current over one time period divided by the time period. I_ avg = 1 T ₀^ T I₀ ( t) dt Since the area under the positive half-cycle is equal and opposite to the area under the negative half-cycle, the integral evaluates to zero. I_ avg = 0 The given values of r.m.s current and frequency are not required for this calculation. Answer: Zero
