What are the different types of silicon diodes?
Silicone diodes are a specific type of diode. There are not any different types of silicone diodes to choose from.
Jntuk 2009 may ptsp solved question paper?
1. a) A box of 30 diodes is known to contain five defective ones. If two diodes are selected at random without replacement, what is the probability that atleast one of these diodes is defective
What is the effect of temperature on frequency of tuning fork?
The effect of temperature on the frequency of a tuning fork is slight, for the length of the tines is little changed. A steel tuning fork would not be used as a precision frequency reference, though quite adequate for audio purposes. As the temperature increases, the lines will lengthen, and the frequency will decrease.
Different types of pn junction diode?
n-p-n and p-n-p junction diodes
Why does mercury go up or down in a thermometer?
The mercury in the bulb at the bottom of the thermometer expands or contracts depending on the amount of heat (the temperature). The narrow calibrated tube that you read the temperature on acts to amplify this effect. The calibration is usually either in Fahrenheit or Celsius.
What was the major effect of replacing the two diodes with resistors?
As I have no information on the circuit I can make no valid predictions as to the effect of replacing diodes with resistors. However I assume the effect(s) will resemble that of having very defective diodes in the circuit.
What is the effect of temperature on PN junction diodes?
As temperature rises more minority carriers are created, causing leakage across the junction to rise. This can cause runaway and eventual destruction of the junction.
What effect temperature?
effect of temperature
What is the effect of temperature on elasticity?
effect of temperature on elasticity
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.
Explain why diodes melt?
Diodes, like many other electronic/electrical components, will melt if the temperature is high enough. This would occur if the power dissipation were too high because the current was too high.
Difference between power diode and simple diode?
Major Differences1- DesignSimple diodes consist of a simple PN junction. They are smaller in size and lighter in weight, while power diodes are in modified form and they are larger and heavier normally. Power diodes are usually available in metal form.2- Voltage RatingSimple diodes are used in normal low power components so they have a relatively low voltage ratings as compared to power diodes. Power diodes can have very high voltage ratings usually in thousands of volts.3- Current RatingPower diodes have a high hand in Current ratings over normal diodes , that can be in several hundred amperes.4-TemperatureMajor probelm in handling high power applications is the generation of heat and temperature. Power diodes have the accessiblity of operation at higher temperature whereas normal diodes do not need this feature in high priority.5- CostPower Diodes are costly as compared to the simple diodes due to the additional components and features.
What are the major classification of diodes?
1. general purpose diodes 2. fast recovery diodes 3. schottky diodes
How does common emitter transistor show more temperature variation than common base transistors?
A transistor is made up of two diodes back-to-back. In a common base circuit - the load is shared between two diodes
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.
Are diodes rectifiers?
No. Diodes are diodes. One diode can be USED as a half-wave rectifier. Four diodes can be used to build a bridge rectifier.
Does temperature effect plastic?
yes, temperature does effect plastic if it gets to hot it can melt it.
