What will happens if zener diode and resistance are connected in parallel?
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.
Is a zener diode a current limiter?
No. A zener diode is a voltage limiter. Circuit design might create a current limiting response, but the basic control is voltage, not current.
What condition under is a diode never intentionally operated?
In the reverse-bias condition, the negative terminal of the source is connected to the anode side of the circuit and the positive terminal is connected to the cathode side.

How does the cut in voltage effects the output of a diode clipper?
For answering this question we have to consider the constant voltage drop model of the diode which says that if voltage across diode is less then its cut in voltage than assume diode to be open circuit and if it is greater then assume diode to be short circuit.Till the input voltage is less than the cut in voltage, diode is open circuit(thus no current through the circuit). Thus entire input voltage appears across the diode as output.When input voltage is greater than or equal to cut in voltage, then short circuit the diode. Thus, there will be no voltage drop across the diode as output.Thus cut in voltage decides when to consider the diode open circuit and when short circuit. It decides when the diode will have output when it will not.
How is a zener diode connected in a cicuit to regulate voltage?
Zener is connected in parallel to the circuit
Why diode should be connected in anti-parallel with thyristor in inverter circuit?
A diode is connected in anti-parallel with a thyristor in an inverter circuit to provide a path for reverse current during the thyristor's off state. This configuration allows the diode to conduct when the voltage across the thyristor becomes negative, ensuring safe operation and preventing damage to the thyristor. Additionally, it helps in managing the switching characteristics and improves the overall reliability of the inverter circuit.
When a 3.3 V zener diode is parallel with a 7 V zener diode what is the break down voltage?
Since they are in parallel, the 3.3V zener diode will "kick in" first when you reach 3.3V, and the circuit will pretty much act the same as if the 7V zener diode isn't there at all.
What is free wheel diode?
A freewheeling diode, also known as a flyback diode, is a semiconductor device used to protect circuits by providing a path for inductive kickback current when the current through an inductive load (like a relay or motor) is suddenly interrupted. This prevents voltage spikes that could damage other components in the circuit. The diode is connected in parallel with the inductive load, allowing the stored energy in the inductor to dissipate safely. It is commonly used in switching applications to enhance circuit reliability.
What will happens if zener diode and resistance are connected in parallel?
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 the current of a circuit if the voltage is 10V with a 1.2K Resistor and a diode?
you should specify: - circuit topology, I assume a series connection. - diode allows current flow? It depends how it's connected - diode forward voltage drop value if diode is in forward conduction, you have VR=10V - VDIODE and, thus, I = VR/R=(10-Vdiode)/1200.
What is circuit diagram of reactifier?
A rectifier is at least two diodes, one anode is connected to the other diode's cathode. ANSWER: Any single diode can be a rectifier without being double or quadruple
Can a diode power a circuit?
An ordinary diode, no. It has nowhere to get energy from.But a solar cell is a type of diode that converts light to electricity. So it is a diode that can power a circuit. So yes, there is one type of diode that can power a circuit.
Explain the use of a varactor diode in a parallel resonance circuit?
Short answer: By using a varactor diode as the capacitance in a parallel resonant ckt, by changing the reverse bias voltage you change the value of capacitance which in turn changes the resonant frequency. This makes a tuneable resonant ckt.
What is unbiased diode?
when we do not apply any source of energy or electricity than a Dodie is said to be un biased Dodie.
When electric circuit is closed no current flow through it IS the statement is correct?
yes... this is possible if a diode i connected in reverse bias with a battery and a resistor for example. A diode in reverse bias means its anode will be connected to positive terminal of the battery and its cathode to the negative terminal of the battery. In such a case, minimal current flows through the circuit which can be neglected.
Is a zener diode a current limiter?
No. A zener diode is a voltage limiter. Circuit design might create a current limiting response, but the basic control is voltage, not current.
