Difference between 1N4007 and 1N4005 diode?
THE 1n4000 series are classified as rectifiers for low frequency use having a big capacitance at the junction the other are diodes that have a very small capacitance therefore a quick disconnect time from conducting to off.
Discussion of zener diode a voltage regulation?
A zener diode has a relatively flat voltage to current curve when reverse biased. Within limits, you can consider that the voltage across the zener diode is constant. You can use the zener as the primary regulator, so long as you consider the power requirements and dissipation of both the zener and the load, and you do not overload the zener. More often, the zener is used as a voltage reference in a larger power supply that uses other components, linear or switched, to supply the load.
Why does we use 250ohms with power supply for the instrument calibration?
We use the 250 ohms with the power supply because the internal resistance of a DC power supply is insufficient to develop a resistance.
Can dc to ac converter burn up power tools?
They can. Low end inverters often use a square wave output, instead of a sine wave output. This causes harmonic distortion that can sometimes damage equipment. One of the damage mechanisms is the simple rectifier - when the diode conducts and recharges the filter capacitor in a power supply, if the slope of the step change is vertical, as it would be with a square wave, the instantaneous current through the diode and capacitor tries to be infinite, and that can damage the diode or capacitor.
Where you use diodes in domestic?
as diode allows current to flow only in one direction . it is highly used in the conversion ac to dc power supply as in chargers, voltage converters... also used in circuit isolation, as it does not work in reverse biased mode.

Why use blocking diode across the relay coil?
Coils have the strange property that when electricity is released from them, they reverse polarity and spike the remaining current back towards the source. The diode is there to "block" this from hitting the power supply and potentially causing damage.

What is the function of a zener diode in a dc power supply?
zener diode use as power regulator and it removes the small pics generated while the time of conversion by rectifies supply from AC to Dc...it is compulary to fixed a zener diode with rectifiier circuit for the protection of electronics devices....we all know that all electronics eqiupments arework on DC... on more think zener diode available in the series of 74XX ..i hope u satisfied.. ANSWER: It uses its own controlled breakdown voltage as a regulator since the voltage remains the same while current may go up or down caused by the varying input
What are the 3 basic types of connectors on a PC power supply?
AT Power Supply - still in use in older PCs.ATX Power Supply - commonly in use today.ATX-2 Power Supply - recently new standard.
What is the use of a power supply?
power supply is a device that supplies electric power to electrical load
Why does we use 250ohms with power supply for the instrument calibration?
We use the 250 ohms with the power supply because the internal resistance of a DC power supply is insufficient to develop a resistance.
How do you troubleshoot a computer power supply?
Use a power supply tester. You can get them on ebay for under $5.
When do you need to replace the computer power supply?
When your computer will not power on. When the cooling fan of the power supply has failed. When the amount of hardware in use in your case exceeds the power capability of your power supply.
What Vcv Stands For in Electronics?
if you are reffering to Vcc than it means- It is the positive power supply used for TTL gates it is nothing but simple dc power supply. if we use CMOS than we use Vdd for indicating power supply these are method for indicating power supply.
Why you use diode in electronics circuits?
You use a diode in a circuit to make sure that if the power was reversed it would not destroy the components, it can also be used to emit light. Its main use is that it is that positive energy can only enter from one side.
