The most common function of a diode is to allow an electric current to pass in one direction (called the forward biased condition) and to block the current in the opposite direction (the reverse biased condition).

∙ 15y agoA diode is a non-linear electronic device which is capable of acting as an electrically controlled switch. It is named so because, it has two electrodes, namely anode and cathode or P terminal and N terminal. Diodes also act as variable capacitance devices, due to their internal capacitances.

∙ 12y agoThere are many different types of diodes, with different functions. One of the simplest is the rectifier diode, which only allows current to pass in one direction, not in the other - so it is an important part of the process of converting AC into DC.
A diode can also be used as a clamp, and as a detector (mixer) in an a.m. receiver.

∙ 12y agoa diode in a ckt basically acts like a switch!! it acts like a switch in on position i.e a short when forward biased and acts like a open ckt or a swich in off position when it is reversed biased!! its used inanalog circuits to generate different types of waves.........

What is the function of a diode?
A diode is basically any of a great variety of circuit element that has two electrical connections. They serve many different functions. The simplest type, the rectifier diode, only lets current through in one direction - but there are other specialized diodes, like the LED (light-emitting diode), to name but one. A diode can also be used as a clamp, and as a detector (mixer) in an a.m. receiver.
What is the difference between a silicon diode and a germanium diode?
The silicon diode (unless its a Schottky diode) conducts at approximately 0.6 volts. The germanium diode, however, conducts at a much lower voltage, typically 0.2 volts. This means that the germanium diode is better at small signal rectification applications, such as AM radio detectors, allowing a smaller tuner tank circuit.
What is the function of photodiode?
the function of a photodiode is produce some reverse current in the external resistor of circuit.
What happens if the temperature of a diode increases?
When the amount of current passing through a circuit increases, it generally increases the temperature, and consequently the resistance. Simply stated, it is harder for the current to pass through the circuit if the temperature increases. The Large Hadron Collider uses superconductors to pass current to its electromagnets. A superconductor passes current through its circuit materials with almost no resistance at all, generally by supercooling the circuit materials.
What is the conclusion for report of classic astable multi-vibrator circuit or LED flasher circuit of 9V with 2 transistors?
It is a circuit that function in only two states, on and off...but it will never be stable
Does zener diode utilize a larger current?
A zener diode, in the reverse bias condition, presents a higher voltage. The current, however, is a function of the supplying circuit.
What is the function of diode what is the function of diode?

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.
What is the function of diode detector?
the function of a diode detector is to detect stuff

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.
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.
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.
