AC, or alternating current, is when the current's voltage varies as a sine wave, say alternating from 120 V to -120 V with a period typically on the order of microseconds. Some devices, however, have a maximum current, typically much less than 120 V. In this case, a "diode limiter" is used. The diode limiter is essentially a circuit that does nothing when the voltage is between 0 V and whatever the maximum specified voltage is, but "clips" or "limits the voltage above that. So after, say, 20 V, the sine wave flattens out and is a straight line until it starts to decrease down to -20 V, at which point it becomes a flat line again. Such circuits are made by diodes (hence the name), which are primarily used for turning AC current into DC current.

How is zener diode different from a conventional diode or ideal diode?
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
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 is more referred to use si diode or a ge diode?
silicon diode is preferred more when compared with germanium diode because in silicon diode the operating voltage is 0.7v where as in germanium diode the operating voltage is 0.3v , germanium is temperature sensitive so it can be easily destroyed by increasing temperature hence silicon diode is preferred more
What are the characteristics of a Gunn diode?
characteristics if gunn diode
What are application of zener diode?
Applications of Zener diode: a.)It Regulators. b.)It Controlled Comparators. c.)It Limiters. d.)It is Part in Power Supplies.
Why put rev-limiters on cars?
Rev limiters prevent damage to the engine caused by high revs.
What is diode and define some of its applications?
a diode is any electronic device that conducts current significantly better in one direction than the other. it can be a vacuum tube diode, a gas filled tube diode, a point contact semiconductor diode, a junction semiconductor diode, any of several metal oxide diodes, etc.typical applications are:AC power rectifiersAmplitude modulated radio signal demodulators (detectors)Gas filled tube diodes used to be used in certain types of digital counters and computer registersDigital logic gatesSign detection circuits in analog computersVoltage clamps and clippersFrequency modulated radio amplitude limiters to remove static and interferenceetc.
What is the primary rate limiter for running?
Rate limiters retard or impede development. In running the primary rate limiters are self-organizing, muscle endurance, and muscle strength of each individual.
What are some applications of Zener diode?
A zener diode is like a regular diode when connected in forward bias which means it will control the flow of the electricity throughout the circuit. Usually you'd find a zener diode in a reverse bias mode because of its purpose which is it has a breakdown voltage value of 5.6v; this shows that the circuit output voltage will be regulated at the same value of 5.6v. It also has the ability to change its own internal resistance based current flow passing through it helping sustain a fixed voltage of 5.6v. The benefits of a zener diode are that it is a less cost effective voltage regulator, its simplicity is based on the fact it's a diode with two overall purposes. The main purpose of a zener diode is to maintain a fixed voltage; in order for this to happen it must lower or raise its resistance depending on the actual current flowing throughout the circuit. If the current increases the zener diode will raise the resistance in order to maintain the fixed voltage. If the resistance lowers the diode will raise it because the fixed voltage should be at 5.6v, and works in reversed biased.
Do all cars have speed limiters?
They are called governors and the answer is no, not all cars have them.
How is zener diode different from a conventional diode or ideal diode?
zener diode :zener diode operates under reverse bias voltageideal diode :ideal diode operates under forward bias voltage
How do you govern the speed of an automobile other than by the operator?
Many cars have speed limiters or RPM limiters to protect their engines from falling apart and destroying themselves. One can buy speed limiters that can be attached to the engine/ignition/fuel control. By fitting a throttle restrictor. This would have to be custom made, most garages would be able to do this work.
Can a diode be used as rectifier diode?
yes, diode can be used as rectifier diode to convert ac to dc
What is impatt diode?
The read type diode are called impatt diode
What is the function of diode what is the function of diode?
A diode is used primarily as a Rectifier
Which is better light emitting diode or laser diode?
Laser diode
