diode conducts in forward bias.so it is on switch.
in reveres bias it will not conduct.so it is off switch
another name for diode is "pn" junction.
diode is unipolar
no....is n't
there are many uses. one major use i remember is in rectification i.e convert ac to dc For switch operation
zener diode
Diode is made of P and N type semiconductors having PN junction. The question is meanigless.
when a semiconductor is doped with p-type and n-type impurities, a pn junction is formed which acts as a diode and prevents the charge carriers to flow to either side of junctionpn juction diode is a semiconductor device that allows current to flow only to one direction.
The junction formed by the combination of a P- type & N-Type material in known as PN jn diode. It is used as a switch as well as a rectifier.
I cannot think of any, but a pn junction is a part of a diode and has a rectifying properties.
the material in which using for doping is already neutral.,,so the pn-junction diode also neutral........
We use pn junction diode in rfctification as a rectifier becase it allows current to flow in one direction only, i.e. in forward biase only , and stop current to flow in reverse baised. thats why we use pn junction diode in rectification.
A diode is voltage and current sensitive it follows an exponential curve and lower then .6v it is considered off and above .6v is considered on.
