If a square signal of $10 \ V$ (varying from $+5 \ V$ to $-5 \ V$) is applied to a $P-N$ junction diode as shown,the output signal across $R_L$ will be:

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

For the given circuit shown in the figure,to act as a full-wave rectifier: $a.c.$ input should be connected across .............. and .................,and the $d.c.$ output would appear across ............. and ..................

Which of the following circuits provides full wave rectification of an $ac$ input?

Which of the following figures represents a half-wave rectifier?

In half-wave rectification,what is the output frequency if the input frequency is $50 \;Hz$? What is the output frequency of a full-wave rectifier for the same input frequency?
