$A$ $p-n$ junction diode $(D)$ shown in the figure can act as a rectifier. An alternating current source $(V)$ is connected in the circuit. The current $(I)$ in the resistor $(R)$ can be shown by:

The output form of a full wave rectifier is

In a full-wave $P-N$ junction diode rectifier,a load resistance of $1500 \ \Omega$ is used. No filter is used. Assume each diode has a forward resistance $R_f = 10 \ \Omega$ and a reverse resistance $R_f = \infty$. When an input voltage with an amplitude of $30 \ V$ and a frequency of $50 \ Hz$ is applied,what are the peak,average,and $RMS$ values of the load current,respectively?

$A$ bridge rectifier is shown in the figure. Alternating input is given across $A$ and $C$. If the output is taken across $BD$,then it is

The output current versus time curve of a rectifier is shown in the figure. The average value of the output current in this case is

The figure below shows a circuit and its input voltage $V_i$ as a function of time $t$. Assuming the diodes to be ideal,which of the following graphs depicts the output voltage $V_o$ as a function of time $t$?
