$A$ full-wave rectifier circuit is operating from $50 \text{ Hz}$ mains. The fundamental frequency in the ripple output will be: (in $\text{ Hz}$)

An ideal diode is connected in a circuit with resistance $R = 50\ \Omega$ and battery $V = 10\ V$ as shown in the figure. What are the maximum and minimum values of the output voltage when no load is applied?

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 $t$?

As shown in the figure,the input is applied between $A$ and $C$,and the output is taken between $B$ and $D$. What should the output be?

If in a $p-n$ junction diode, a square input signal of $5 \,V$ to $-5 \,V$ is applied as shown, then the output signal across $R_L$ will be:

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
