The reverse saturation current in a p–n junction diode

The depletion region in a p–n junction is so called because it is depleted of,

The motion of charge carriers, across the potential barrier, in a forward and reverse-biased p–n junction, is due, respectively, to

The input resistance, of a pnp transistor, in its common emitter configuration, is given by,

In a bi junction transistor, the base region is,

For a given transistor, if $\beta =200\backslash beta\; =\; 200$, the value of $\alpha \backslash alpha$ will be (almost) equal to

The voltage drop, across a LED, when connected in forward bias configuration to a multimeter, is,

A small device has a yellow-colored capsule top and has 220 written on it. There is no + or – sign on it. This device is likely to be

If negative probe of a multimeter is placed n the base of a p–n–p transistor, then ohm meter reading, with other probe placed on one of the other pins, will show

While checking a diode with a digital multimeter, set to its ‘diode’ symbol, a good diode is expected to show.
