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:

$A$ full-wave rectifier provides a load of $1 \ k\Omega$. The diode is supplied with an $a.c.$ voltage of $220 \ V_{rms}$. If the diode resistance is neglected,the average $d.c.$ voltage and average $d.c.$ current are respectively:
