Which of the following circuits provides full-wave rectification of an $A.C.$ input?

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

In the diode-based rectifier circuit given below, if $V_s=V_m \sin \omega t$ and the diode is ideal, then the average value of $V_L$ is

In a full-wave rectifier circuit, the input frequency is $50 \, Hz$. The fundamental frequency of the ripple is ....... $Hz$.

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?

In the half-wave rectifier circuit shown,which one of the following waveforms is true for $V_{CD}$,the output across $C$ and $D$?
