Bulk resistance of diode depends on how it is biased. The bulk resistance of a diode is the approximate resistance of the diode when it is forward biased.
no we not use resistance in place of diode.
Backward 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 resistance of a diode is .4 ohms is made of tantalum or .7 ohms if made of silicon. ANSWER: THE RESISTANCE OF A DIODE IS SIMPLY V/I the impedance however is defines by Boltzmann constant
If a diode breaks down in the reverse direction then, providing there is current-limiting resistance, nothing will happen to the diode. If there is no such current-limiting resistance the diode will be destroyed. Heat is the only enemy of a semiconductor of this type.
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
A diode is an electronic component with the characteristic that its resistance is not constant, but depends on the magnitude of the current through it. An ideal diode has zero resistance to current in one direction, and infinite resistance to current in the reverse direction.
The incremental resistance of a diode is the inverse of the slope of the V-I curve at the operating point.
After isolating the diode from the circuit, the diode shows infinite resistance in one direction and low resistance in the other direction. The diode
The dynamic resistance of a diode, be it zener or otherwise, will be different from its static resistance because a diode is not a resistor, and resistance is not a function of current flow. It is a diode, and a diode has its own characteristic voltage to current curve, forward and, in the case of a zener, reverse.
What happens depends on the temperature coefficient of the diode. If that diode has a positive temperature coefficient, it resistance increases with increased temperature. A diode with a negative temperature coefficient does the opposite.
no we not use resistance in place of diode.
When the voltage increases the temperature in the diode also increases. When the temperature in the diode increases, the resistance decreases.
the amount of voltage applied to the diode
Backward diode
Diodes are measured in terms of resistance. The formula is as follows Rd = Vd / Id. That is Resistance of the diode = voltage across the diode to current flowing throught the diode.
an average resistance of a diode is the mean average of its statistical values gather with extensive experiments with a plot data resistance average.
