Can you use a rectifying diode to reduce voltage in an AC circuit?
No, you must use one of three options depending upon your circuit and what you want to accomplish: 1. Use a transformer (ie; 24 volts into 12 volts). 2. Use a voltage regulator circuit. 3. Use a ZENER diode that is rated for the maximum voltage you desire in your circuit. Example: A 12 volt circuit with a 5 volt zener diode (the diode will only let a maximum 5 volts get through and will disipate the remaining voltage to ground. (requires proper design and resistor selection). ANSWER: YES ABSOLUTELY if there is a full wave rectifier removing one diode will reduce the voltage and reduce power too.
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.
Practical diode model define and explained?
a way of diode modelling in which diode just work as an energy source in the circuit
What is a ordinary diode?
A diode is an electronic component that will only allow current to flow through it in one direction. It is analogous to the valve in a bicycle tyre, which only lets air in but not out (except when you press the release tab). So if you connect a diode in a simple DC circuit one way around, the circuit will be closed and any devices on the circuit will work. If you connect it the other way around the circuit is open and no current will flow. I presume by 'ordinary diode' you mean a diode that is not a light emitting diode (LED). A LED is just a diode that emits light when current flows through it. Its purpose is to make light. A non-LED diode doesn't emit light. Its purpose is to allow current through a circuit in only one direction. A common use for ordinary diodes is in "rectifying circuits" which convert AC to DC.There are many other uses though.
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.
Explain the operation of a forward bias circuit include any related diagam?
tel me the devices like diode,mosfet,bjt....etc.
Why use a npn transistor in a common emitter bjt single stage amplifier circuit?
You can use an npn or a pnp bjt in a common emitter amplifier circuit. The decision of which one to use is based on whether you want the collector and base to be more positive (npn) or more negative (pnp) than the emitter.
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 use diode in a circuit?
They only allow current to flow in one direction.

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.
Can you use a capacitor instead of zener diode in biased clipping circuit?
No. The purpose of the zener diode is to clip (turn on) at a certain voltage. A capacitor will not exhibit this behavior.
Why UJT's equivalent circuit has a diode?
A UJT is a special type of diode with a long resistive base having 2 contacts and acting as a voltage divider. The diode junction is created at a point on this base selected to set the trigger voltage of the UJT at which it will conduct. Therefore the equivalent circuit has a diode because the actual circuit has a diode.
How do you check if a diode is serviceable?
use a vomm set to infinite resistance if you have reistance one way and not the other way. diode is good (must be isolated from circuit) if no resistance both directions diode D.O.A.
What is diode capacitance?
The max amount of voltage the diode can block from going into the circuit backwards.
