The purpose of a diode is to direct the flow of current in a circuit. Diodes function by allowing current flow in only one direction (acting as a short when current is applied at one end) and resisting current flow from the opposite direction (acting as an open circuit). Electronic devices such as full wave rectifiers use a series of diodes to convert AC to DC current.
What else can I help you with?
Will a zener diode work the same as a germanium diode?
No. An ordinary diode, be it silicon or germanium, conducts in one direction only, whereas a zener diode conducts in both directions, but at different voltages. An ordinary diode is used to rectify, using its forward bias characteristics, while a zener diode is used to regulate, using its reverse bias characteristics.
What is a diode modulator?
A diode modulator is a type of AM modulator constructed using diodes. One type of diode modulator is the ring modulator shown in the image.
Why diode is prefer?
the most important character of diode is ,it allows only uni directional flow.. we can prefer diode in place of our commonly using electronic switches.
Is it possible to check diode and zener diode in laboratory?
yes, of course it is. one way is using a curve tracer.
How do you make a pn junction diode using czochralski technique?
It is difficult
Can you use transistor as diode?
its the simplest thing to do. There are three legs in a transistor, one each of collector, base and emitter. So if you need to use it as a diode, just connect either collector-base or emitter-base. Say, if you use an NPN transistor, then the base region will be the anode of diode and emitter or collector will be the cathode of the diode.
How can a diode be made?
a diode can be make using p-n junction....form a p junction n form a n junction...and after joining them u cn make a p-n junction diode....for making a diode u ll ve to face doping problems
What is an Esaki diode?
A diode is a semiconductor electrical component that allows an electric current in only one direction. A tunnel diode, or Esaki diode, is a special type of diode that can operate very quickly using quantum tunneling, allowing it to work even with microwave frequencies (current switching direction billions of times per second).
What if a semiconductor diode is being tested using a digital multimeter and the resistance of the diode is 10 ohms in both forward and reverse-biased conditions is the diode shorted or opened?
The diode is neither shorted nor open. It is a zener diode and it is conducting in both directions. If it were truly shorted, it would read closer to zero ohms in both directions.
Germanium diode IN34?
Yes, I am using one in my electronics class currently
How do you use a diode as temperature sensor?
The voltage across a Silicon Diode junction varies 0.00011 volts per degree Kelvin. Connect the diode to a high gain amplifier and the output of the amplifier to a DVM using an appopriate voltage scale.
How do you find the ac resistance of a diode?
The ac resistance of a diode is found using the equation: (The change in Vd)/(The change in Id) An easier was is to use the Equation: 26mV / Id. This is a general form as the ac resistance of a diode change as the temperature changes.
