What are the intrinsic and extrinsic diodes?
Intrinsic diodes are formed by a p-n junction within a single semiconductor material, while extrinsic diodes are formed when impurities are added to a semiconductor material to alter its properties. Intrinsic diodes have natural electrical properties, while extrinsic diodes have controlled electrical properties based on the type and amount of impurities added.
What is negative resistance region?
Negative resistance region refers to a region on a current-voltage characteristic curve where an increase in voltage leads to a decrease in current. This phenomenon is opposite to what is expected in regular resistors, where an increase in voltage typically results in an increase in current. Negative resistance can be created in certain electronic components, such as tunnel diodes, and is used in various electronic applications like oscillators and amplifiers.
Why would you use silicon diodes instead of germanium?
Though germanium diodes were the first ones fabricated, several factors make silicon the choice vs. germanium diodes. Silicon diodes have a greater ease of processing, lower cost, greater power handling, less leakage and more stable temperature characteristics than germanium diodes. Germanium diodes' lower forward drop (.2V to .3V versus .7V to 1.0V) make them better at small signal detection and rectification.
What is true about diodes?
Lots of things are true about diodes. There are different types of diodes; their general characteristic is that they have two electrodes (electrical contacts). They conduct current in one direction only.
What is the difference of silicon diode and germanium diode?
A silicon diode has a voltage drop of approximately 0.7V, while a germanium diode has a voltage drop of approximately 0.3V. Though germanium diodes are better in the area of forward voltage drop, silicon diodes are cheaper to produce and have higher breakdown voltages and current capabilities.
What is the typical bulk resistance of rectifier diodes?
101902kb ohm
What reverse resistance reading should diodes have when under test with an ohmmeter?
Reverse resistance should be infinite.
Why different transistor have different resistance?
Because they are different transistors. Resistance among their internal diodes is one of the main features of a transistor.
What is dynamic resistance of diode?
The Current-Voltage relationship of a diode is not constant (not a straight line) and hence the resistance cannot be measured. Due to this non-linear nature of the the curve, there exists a unique value of resistance at every point of the curve which is called dynamic resistance (not static of constant resistance). The dynamic resistance equals the change in voltage divided by the change in current, when the voltage is changed by a small amount. In other words it is the slope of the graph of voltage against current. The dynamic resistance is different at different current values. About 30 years ago, and I do not remeber the brand or maker, there was a digital multimeter that DID measure dynamic resistance in diodes. It was a God Send for testing diodes in circuit. Diodes only conduct in one direction, so the device would show an open in one direction and a resistance under 1000 ohms on the other or a short (0 ohms).
What unit is a Diode measured in?
Diodes are measured in terms of resistance. The formula is as follows Rd = Vd / Id. That is Resistance of the diode = voltage across the diode to current flowing throught the diode.
What is ac and DC resistance of a diode?
diodes follow an exponential curve meaning non linear in nature. by using Boltzmann formula an impedance can be calculated. That would be the AC Resistance the dc resistance on any device is the voltage drop divided by the dc current.
What type of diode exhibits negative resistance?
A Tunneldiode, usually made of GaAS. In a part of its curve it has a negative resistance. This means that when you increase the voltage in that region, the current will drop.
What are the major classification of diodes?
1. general purpose diodes 2. fast recovery diodes 3. schottky diodes
Which diode will work when two different diodes are in parallel?
the path of least Resistance electricity is like water it flows in the direction of least Resistance so current should flow in the diode with the lowest Resistance but if the draw on current was high enough it would also start to flow in the higher resistance diode
How do you trouble shoot generator problem if there is no output?
Short the windings and perform resistance testing. Check your rectifier for shorted and/or opened diodes (likely open).
What are examples of diodes?
There are so many different types of diodes. Some of the common examples include light emitting diodes, silicon diodes, zener diodes and so many more.
What is the importance of diode?
the important of diode in electrical circuit is to,,flow the current being regulated to the resistance of the electricity ,,from ac to dc..
