The frequency of the input $a.c.$ of a full-wave rectifier is $50\,Hz$. The frequency of the output is.....$Hz$.

In the circuit shown in the figure, the maximum output voltage $V_0$ is.....$V$.

$A$ rectifier is used to

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?

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 $t$?

$A$ diode detector is used to detect an amplitude modulated wave of $60\%$ modulation by using a condenser of capacity $250\, pF$ in parallel with a load resistance $100\, k\Omega$. Find the maximum modulated frequency which could be detected by it.
