In the equations v = \(\sqrt2\)V sin wt and i = \(\sqrt2\)I sin(wt – θ), θ is in _______

In the equations v = \(\sqrt2\)V sin wt and i = \(\sqrt2\)I sin(wt – θ), θ is in _______ Correct Answer degree

The equations of voltage sine wave and current sine wave are given v = \(\sqrt2\)VRMS sin wt and i = \(\sqrt2\)IRMS sin(wt – θ) respectively. In all these θ is the angle between voltage and current. θ is expressed in radian and not in degree. This angle θ indicates whether current is lagging or leading the voltage; and accordingly is positive or negative. If the value of θ is given in degree, it is to be converted to radian before inserting or substituting in the voltage or current equation.
