In the equations v = \(\sqrt2\)V sin wt and i = \(\sqrt2\)I sin(wt – θ), what does I indicate?
In the equations v = \(\sqrt2\)V sin wt and i = \(\sqrt2\)I sin(wt – θ), what does I indicate? Correct Answer RMS current
The equations of voltage sine wave and current sine wave are given by v =Vmsin wt and i = Im sin(wt – θ) respectively. In these equations Im signify the maximum current of current. Again RMS currents is given by IRMS=Im/\(\sqrt2\). On substituting the maximum current with RMS component, we get the equation i = \(\sqrt2\)IRMS sin(wt – θ). Hence in the given equation I indicates RMS current, not otherwise. We use this RMS value in various calculations of power in ac circuits.
