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 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 reverse resistance $R_r = \infty$. When a sinusoidal voltage with a peak amplitude of $30 \ V$ and frequency $50 \ Hz$ is applied, calculate the $D.C.$ power output and $A.C.$ power input respectively.

If the following input signal is sent through a $PN$-junction diode,then the output signal across $R_L$ will be:

$A$ bridge rectifier is shown in the figure. Alternating input is given across $A$ and $C$. If the output is taken across $BD$,then it is

$A$ 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.

What will be the output waveform for the rectifier shown in the figure?
