What is the purpose of the diode in the GM AC clutch circuit?
The purpose of the diode is to prevent electricity to flow in the wrong direction in a circuit. The purpose of the diode is to prevent electricity to flow in the wrong direction in a circuit.
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.
How is a non-conducting diode biased?
A nonconducting diode is biased in the reversed direction (reverse polarization).
Practical diode model define and explained?
a way of diode modelling in which diode just work as an energy source in the circuit
When a 10mA forward bias current and the voltages at the anode and cathode of a diode in a circuit are found to be the same what is the diode most likely to be?
With a 10mA forward bias current, if the voltages at the anode and cathode of a diode in a circuit are found to be the same, then the diode most likely to be shorted.
If a diode is connected to a battery and a lamp what happens when the diode direction is reversed?
I diode allows current to flow in only one direction. Therefore, if a lamp is "on" in a DC circuit, and the diode in series with the lamp is reversed, the light will be turnned off due to the diode blocking current flow (unless the voltage is above the breakdown voltage of the diode - if this is the case, the diode will fail). If this is an AC circuit, every half cycle the diode will turn on, then the next half cycle it will turn off. To your eye, the bulb will most likely appear slightly dim due to this on then off cycling. If the diode is reversed, there will be no apparent change. The difference is the half cycle the diode would have been off before reversing, it will now be on, etc.
When reversed biased a diode acts like an open circuit?
The key function of a diode is to control the direction of the flow of current. Current passing through a diode can only go one way, which is called forward biased. In this setup, current is continuous hence the circuit is closed. When there is no current passing through, there will be no flow, and this is called reversed biased. In such a case, current is not continuous, hence it is called open circuit.
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.
Why you use diode in electronics circuits?
You use a diode in a circuit to make sure that if the power was reversed it would not destroy the components, it can also be used to emit light. Its main use is that it is that positive energy can only enter from one side.

What is the forward voltage of a silicon based zener diode?
It would be 0.7V, the same as any other silicon diode; except for one thing, most zener diodes are manufactured with a reversed diode in series with them. When the zener is operated in its normal zener breakdown mode this reversed diode conducts, letting the zener operate. When the zener is operated in its forward biased mode this reversed diode prevents conduction. Thus most zeners have no forward voltage.

What happens to the load if reverse the polarity of diode?
if you reverse the diode in a half wave rectifier, you would expect the A- Ripple to increase B- output to be less filtered C- out put polarity to be reversed D- output voltage to decrease
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.
