Question

Two alternating currents are given by `i_1 = i_0 sin wt and i_2 = i_0 sin (wt + pi/3)` Will the rms values of the currents be equal or different?

Answer 1

The rms value of current is given by,
`i_{rms} = (i_0)/sqrt(2`
Since peak value of current i₀ is same for both currents, their rms values will be same.
