When $p$-type and $n$-type semiconductors are brought into contact,they form a $P-N$ junction which acts as a .........

In the circuit shown below, the voltage appearing across the diode $D$ will be of the form:

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?

$A$ diode is used as a/an

$A$ full-wave rectifier with diodes $D_1$ and $D_2$ is used to rectify $50 \,Hz$ alternating voltage. The diode $D_1$ conducts .......... times in one second.

For the circuit shown in the adjoining figure,to act as a full-wave rectifier,the $AC$ input should be connected across $....$ and $....$ and the $DC$ output would appear across $....$ and $....$.
