What is break down region of zener diode?
Zener breakdown is the phenomena wherein the Zener diode experiences reverse breakdown at a much lower voltage than a normal diode, which may breakdown in excess of 100 volts, depending on the type. This is useful because the Zener will hold the same voltage after breakdown, regardless of the input voltage, making them excellent for voltage controlled switches and references.
How a bucking voltage acts?
bucking voltage is a voltage which is of opposite polarity to the voltage it acts .
What is voltage transformation ratio?
ratio of secondry voltage to primary voltage is called voltage transformation ratio
What is the voltage that supplies a motor starter called?
In the electrical trade it is called control voltage. This voltage can be any voltage. In North America the common control voltage is 120 volts.
How do we adjust the voltage of a shunt generator?
The voltage is adjusted with a potentiometer that adjusts the field voltage through the voltage regulator.
What is the cause of excess voltage?
Maybe the power source...
What is the difference between a voltage converter and a voltage regulator?
the difference between a voltage converter to a voltage regulator,is that a voltage converter,converts or changing the desired voltage to be used while the voltage regulator,regulates the input of the voltage amount not to excess to its inputs.
What would cause a varistor to burn?
Overload - excess voltage causes excess current, and the combination causes excess power dissipation, leading to overheating. If the varistor was included to help dampen voltage surges, then a very "dirty" supply. with large numbers of surges, can lead to overheating.
Why resistance is use in circuits?
To prevent excess voltage to enter in a diode or LED etc
What is voltage regulater and its working?
Voltage regulator is a device which regulates the voltage or maintains a stable voltage irrespective of the fluctuations caused in the main line voltage. It contains a diodes and a capacitor. The capacitor discharges whenever there is a downfall of voltage in the main line and it keeps on charging the remaining time. the diode avoids the excess voltage to enter the circuit thereby maintaining a constant voltage.
WHAT IS An excessive amount of electrons at one end of a conductor and deficiency at the other?
Voltage <><><><><> Actually, an excess or deficit of electrons is called a charge. It is measured in coulombs. Voltage is joules per coulomb, meaning that voltage is energy per charge.
What is the purpose of using the series resistance in a clipping circuit?
something to drop the excess voltage across while clipping.
What resistance does a practical diode offer under reverse-biased conditions if the applied reverse voltage is greater than the breakdown voltage?
A normal diode with reverse voltage in excess of its rated breakdown voltage could fail. Resistance could be high (blown open) or low (shorted).
Where does excess electricty go?
There is no excess "electricity". Excess (or a deficit of) electrons end up as a static charge. "Extra" current in a wire occurs at a phase angle other than the phase of the applied voltage, but this energy is largely recovered (being essentially "imaginary power").
Is voltage an excess accumulation of electric charge?
Sort of ... 1) Voltage is ALWAYS a comparison, thus it requires two reference points. 2) Its the density of the charge that counts, thus a gigantic charge over a very large area would result in a low voltage.
What is electronic breakdown?
Most electronic devices have maximum voltage or current ratings, so if you exceed these maxima, you can expect them to breakdown...ie: Malfunction. Most breakdowns are permanent, so removing the excess voltage or current will not cause them to recover.
What resistance does a practical diode offer under reverse-biased conditions if the applied reverse voltage is less than the breakdown voltage?
A practical diode under reverse-biased conditions, if the applied reverse voltage is less than the breakdown voltage, will offer a high resistance, usually in excess of 10 megohms. In a practical circuit, the diode would appear to be open.
