For the given electric voltage signal,the $dc$ value is......$V$.

The output in the circuit shown in the figure is taken across a capacitor. The input signal is as shown in the figure.

In a rectifier circuit,the filter circuit:

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

Match List $I$ with List $II$.

List $I$	List $II$
$(a)$ Rectifier	$(i)$ Used either for stepping up or stepping down the $a.c.$ voltage
$(b)$ Stabilizer	$(ii)$ Used to convert $a.c.$ voltage into $d.c.$ voltage
$(c)$ Transformer	$(iii)$ Used to remove any ripple in the rectified output voltage
$(d)$ Filter	$(iv)$ Used for constant output voltage even when the input voltage or load current change

Choose the correct answer from the options given below:

$A$ 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:
