When the signal reaches point e, the input voltage can be expected to be more
than the capacitor voltage. When the input signal moves from e to f the capacitor
gets charged to its peak value again. The diode gets reverse biased and the
capacitor starts d

When the external voltage applied to the junction is in such a direction the
potential barrier is increased it is called reverse biasing.
To apply reverse bias, connect ve terminal of the battery to p-type and +ve

rectified is applied to the primary of the transformer and the d.c. output is taken
across the load RL.

If the type of diode is not specified then assume the diode to be of silicon type.
For an ideal diode, forward resistance rf = 0 and cut-in voltage, V = 0.
We know that the output of the rectifier is pulsating d.c. i.e. the output obtained b
