A resistance is connected in series with p-n junction of diodes to limit the number of electrons that flow across the junction.
If diode is connected in series then current will flow only in one direction. ie. Current flow occurs only when diode is forward biased. ANSWER: It depends are the diodes are connected in series if they are back to back no current will flow if connected in the forward conduction mode then they will conduct.
The input resistance of a trasister is jst like pn junction of a diode which has a breakdown voltage of .7v for silicon and the output resistance is like a reverse bias of a diode and hence the resistance is high
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
we can conclude that the standard diode conducts current when connected in forward bias mode.
zener diode
To drop the unwanted voltage.
because that the tunnel diode is a standard pn junction diode in many respect except its highly doped pn junction so it has some characteristics in the negative resistance region another that its a standard diode
The resistance of a forward biased pn junction is zero.
If diode is connected in series then current will flow only in one direction. ie. Current flow occurs only when diode is forward biased. ANSWER: It depends are the diodes are connected in series if they are back to back no current will flow if connected in the forward conduction mode then they will conduct.
A thin junction diode which exhibits negative resistance under low forward bias condition is known as tunnel diode.
A thin junction diode which exhibits negative resistance under low forward bias condition is known as tunnel diode.
Consider ideal diode to be connected in series with resistor of 6kSilicon diode forward bias voltage = 0.7 voltsCurrent across 6k resistor = (5-0.7)/6000 amperesVoltage across {resistor + diode}=4.3 + 0.7=5vIf silicon internal resistance is 6k then voltage across diode=5vIf external resistance is 6k and diode resistance is negligible then voltage across diode=0.7v
The input resistance of a trasister is jst like pn junction of a diode which has a breakdown voltage of .7v for silicon and the output resistance is like a reverse bias of a diode and hence the resistance is high
The junction (diode or transistor) will be destroyed.
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
It's a rectifier diode made simply by combining P type and N type silicon. Where the two are joined, forms a junction that allows conduction in one direction only. A pn junction diode is a diode obtained by by dopping a silicon crystal through the process of covalent bond.
we can conclude that the standard diode conducts current when connected in forward bias mode.
