In the equations v = V sin wt and i = I sin(wt – θ), what does θ indicate?

In the equations v = V sin wt and i = I sin(wt – θ), what does θ indicate? Correct Answer phase angle between current and voltage

The equations of voltage sine wave and current sine wave can be given by v =Vmsin wt and i = Im sin(wt – θ) respectively. In all these θ is the angle between voltage and current. This angle θ plays a significant role in ac power transmission system. It is this angle of difference which decides how much the current is lagging or leading the voltage in ac power flow.
