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.

What is Zener resistance of the Zener diode?
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
What happens when the temperature of a forward biased diode is increased?
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.
Why resistance is connected in series with P-N junction diode?
A resistance is connected in series with p-n junction of diodes to limit the number of electrons that flow across the junction.
Infinite resistance in one direction of Diode?
After isolating the diode from the circuit, the diode shows infinite resistance in one direction and low resistance in the other direction. The diode
Why the dynamic resistance of a zener diode different from its static resistance?
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.
How is a zener diode connected in a cicuit to regulate voltage?
Zener is connected in parallel to the circuit
Why is a resistance usually connected in series with zener diode?
To drop the unwanted voltage.
What is Zener resistance of the Zener diode?
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
Which diode will work when two different diodes are in parallel?
the path of least Resistance electricity is like water it flows in the direction of least Resistance so current should flow in the diode with the lowest Resistance but if the draw on current was high enough it would also start to flow in the higher resistance diode
What happens when the temperature of a forward biased diode is increased?
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.
The bluk resistance of a diode depends on?
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.
How much forward diode voltage is there with the ideal diode approximation?
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
What happens in the circuit when a1N4001 diode experiences its breakdown voltage of 50V?
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.
What happens to the diode if it has high piv?
It can be connected in high reverse bias voltage .
Why resistance is connected in series with P-N junction diode?
A resistance is connected in series with p-n junction of diodes to limit the number of electrons that flow across the junction.
Infinite resistance in one direction of Diode?
After isolating the diode from the circuit, the diode shows infinite resistance in one direction and low resistance in the other direction. The diode
What happens when diode is supplied with a voltage higher than RIV in reverse bias?
when diode is supplied with a voltage higher than RIV in reverse bias, the diode will burn out and will have zero resistance.
