Question
Two alternating currents are given by, $\text{i}_\text{i}=\text{i}_0\sin\omega\text{t}$ and $\text{i}_\text{i}=\text{i}_0\sin\Big(\omega\text{t}+\frac{\pi}{3}\Big)$ Will the rms values of the currents be equal or different?

Answer

$\mathrm{I}_{\mathrm{rms}}$ will be equal because in a complete cycle heat dissipated will be equal for both.
