A single-phase AC voltage controller feeding a RL load has a load voltage of 100 V (rms) when fed from
a source of 230 V (rms) at 50 Hz. The input power factor of the controller is
A voltage of 200cos100t is applied to a half-wave rectifier with a load resistance of 6 kΩ. The rectifier
is represented by an ideal diode in series with a resistance of 1 kΩ. The maximum value of current,
DC component of current and rms value of current will be, respectively
