What way does a diode conduct?

A typical diode has a band on one end of the diode. That is considered the positive end. Current is considered to flow from the negative end to the positive end. In power diodes, they can be of two types-- positive polarity and negative polarity. Power diodes are usually designed with one end of the diode to be mounted in a heat sink. Since the desire is to allow current to flow in only one direction, the engineering of the circuit determines which way the current is designed to flow, hence the designation of positive or negative diodes especially for power diodes. A typical car alternator has 3 positive diodes and 3 negative diodes for a total of six.


What economical device - varistor - transistor etc can you use to supply power to a relay until the voltage drops to 10.5 volts?

A zener diode, a transistor, a rectifier diode, and a few resistors. A 10.5V zener diode will conduct until the voltage across it drops to below 10.5. If the relay is small enough, a zener diode is all you need. However, more than likely the current draw of the coil would burn the zener out. Use the zener to drive a transistor, and use the transistor to trigger the relay. V+ | |_______________________ | | _|_| _____|___ |/ \ 10.5V | | /___\ | 3 Relay | __|__ 3 Coil | / \ 3 0---------- /___\ 3 | | | 3 \ \ 4.7K | | / 2.2K / |____ ___| \ \ | / / | | | B | / C | |________|/ | |\ 2N2222 | | \ | | E |______________________| | _|_ \\\ When the voltage is above 10.5V the zener will conduct ant turn on the transistor. The transistor will power the relay. When the voltage drops below 10.5V the zener will stop conducting, shutting off the relay. The rectifier diode absorbs transients caused by the field breakdown in the coil, protecting the transistor. Just a plain resistor will do it or you may follows suggestion and use a computer to do that. The last time i used those ancient devices i find out they operate as a current device like minimum pull in current source. So a passive resistor in series will insure the minimum pull in source however it could be higher then the 10.5 v you need.The above designi just plain silly.


How can you stop electric current?

An insulative material is one that will stop the conduction of heat. This would be considered a thermal brake and could be a piece of plastic or wood.


What would be the effect of an open resistor in a series circuit with two resisters?

In a series circuit with two resistors, if one resistor becomes an open circuit (meaning it has infinite resistance), the entire circuit will stop conducting current. This is because current can only flow through a closed loop, and the open resistor breaks that loop. As a result, both resistors will have no voltage across them, and the overall circuit will be non-functional.

Why use the PN junction diode in rectifier?

We use pn junction diode in rfctification as a rectifier becase it allows current to flow in one direction only, i.e. in forward biase only , and stop current to flow in reverse baised. thats why we use pn junction diode in rectification.


Can diode be used as transister?

No. A diode can not be used as a transistor. A diode allows electricity to flow in one direction like a one way street. A transistor works the same way as putting a stop light in the one way street. It lets electricity flow at certain times and keeps electricity from flowing at certain times. Of course a diode only works when electricity is there to flow just like a one way street only works when there are cars there to ride through it.

Explain the origin of the reverse recovery charge?

The reverse recovery charge originates from the behavior of diodes, particularly during the transition from conducting to blocking states. When a diode that has been forward-biased is suddenly reverse-biased, it doesn't stop conducting instantaneously; instead, it continues to conduct for a brief period due to stored charge carriers. This phenomenon results in a reverse recovery current, which can cause energy losses in switching applications, leading to the concept of reverse recovery charge. Understanding this charge is crucial for optimizing the performance of power electronics and minimizing switching losses.
