The process by which $ac$ is converted into $dc$ is known as

In comparison to a half-wave rectifier,the full-wave rectifier gives lower

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

$A$ 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.

The figure shows the current as a function of time at the output of a full-wave rectifier. The average value of this current is:

The peak voltage in the output of a half-wave diode rectifier fed with a sinusoidal signal without a filter is $10 \ V$. The $dc$ component of the output voltage is:
