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.
Can a list have only one item?
The word 'list' usually denotes multiple items. However, unless instructed otherwise what's to stop you from having a one item list?
How can the government stop pollution?
They cannot stop it. They can minimise it and legislate against it.
How can we Diode can be used as a rectifier?
A diode is used to stop the negative voltage swing in an AC signal, so you only get the positive portions.diode-rectifier
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.
Will tar paper stop paintballs?
If you had enough layers, yes.
How do you stop black dye from your leather bag from coming off on your clothes?
Try few layers of hairspray, and you have to repeat it from time to time. For me this was the only thing that worked.
What is a level 2 traffic stop?
Some departments have their own "Levels" of calls or traffic stops. So it would all depend on where the traffic stop is and which agency is conducting the stop.
What are the uses for bedrock in the Minecraft world?
The main use for bedrock in the world is to stop you from mining into the void. However, admins and ops can use it on servers to stop players from breaking certain areas as only they can place and break it.
How many layers of house wrap should you use?
One. it is a wind stop not insulation.
How do you stop paintballing from herting?
You can't exactly stop it from hurting but if you wear a chest protector and two layers of pants and shirts it should help.
Why does your radio shack light emitting diode stop blinking after 15 seconds?
A: Check your supply volatge and current . I suggest you have too mauch current
What will stop the flow of electricity?
Turn off the switch, generator runs out of fuel, wind not turning the windmill, solar panel at night, diode, insulation.
