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

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 input a.c. voltage of frequency $60 \,Hz$ is applied to a half-wave rectifier and also to a full-wave rectifier. The output frequency in the case of the half-wave rectifier and that in the case of the full-wave rectifier is respectively:

When a sinusoidal $AC$ voltage is applied to a half-wave rectifier,the peak output voltage is $10 \ V$. The value of the $DC$ voltage in this output is .......

Normally,a capacitor is connected across the output terminals of a rectifier to

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 a reverse resistance $R_f = \infty$. When an input voltage with an amplitude of $30 \ V$ and a frequency of $50 \ Hz$ is applied,what are the peak,average,and $RMS$ values of the load current,respectively?
