What is the purpose of the zener diode in a power supply?
to limit the voltage or regulate the same.
What is voltage regulation of a rectifier?
A: actually a full wave rectifier does not regulate. It will however follow the input minus diodes voltage drops. depending on current it is assumed to be .6 to .7 volts for silicon diodes.
Should the ohmmeter be connected to the circuit while the power is being applied or only when the circuit is turned off?
Turn off the supply before using the ohmmeter,it will damaged your ohmmeter when supply is present.
Full form of DC power supply?
DC Power is Direct Current Power Supply.
Is a 24VDC power supply short-circuit protected?
That would depend on the power supply.
What is line in line regulation?
Line refers to the a.c. supply line. Line regulation is the change in output of a device, usually a power supply, which is due to variations in the voltage of the a.c. supply.
What is another word for soft power supply?
A soft power supply refers to a supply with poorvoltage regulation, which is defined as the ability of a system to provide near constant voltage over a wide range of load conditions. For example poor power line voltage regulation (a soft supply) causes lights in a home to dim each time the refrigerator starts.
What is the equation for the percent regulation of a power supply?
%VR=(Vnl-Vfl)/Vfl X 100
What components define the system's form factor?
The mother board, power supply, and chassis
How do you install an Uninterruptible Power Supply to a computer?
Bond it to a standard regulation fail-proof always-running generator.
What is line regulation?
Line regulation is a measure of the ability of the power supply to maintain its output voltage given changes in the input line voltage. Line regulation is expressed as percent of change in the output voltage relative to the change in the input line voltage.
What is the regulation and why is it important?
A: All electronics are susceptible of noise spikes and outside influences. Regulation of the sources is some guarantee that the noise will not come from that particular source like DC power supply fluctuation. Without any regulation the circuit maybe totally unreliable
What components define form form factor?
For sure, it is the Motherboard, the Power supply, and the Chassis that determines the form factor of a computer.
Does your LCD HDTV need voltage regulation?
Yes, but that regulation is built into the unit. An LCD HDTV either plugs directly into the wall or has a "power pack" that does. In either case, voltage regulation is accomplished inside the unit's power supply section, or in that external power supply. The set is largely immune to line voltage irregularities, except, of course, a power outage or a really big "sag" in the line voltage. In either case, the power supply (either the in-set one or the external one) will do the best it can until the voltage simply gets too low for it to continue to operate, then it "trips" or goes offline to protect the TV. It's that simple. No worries here.
What is the purpose of the zener diode in a power supply?
to limit the voltage or regulate the same.
Define voltage regulation and efficiency of a short transmission line?
Voltage Regulationvoltage regulation of a line is defined as the change in voltage at the receiving end when full load at a given power factor is removed, the voltage at the sending end being kept constant. it is expressed as a fraction or a percentage of the receiving end voltage at full load. it can be written as, Per unit regulation = Vrnl - Vrfl / VrflPercent regulation = (Vrnl -Vrfl / Vrfl) * 100Efficiency of a Short Transmission LineIt is the ratio of the Power Output of the line to the Power Input of the line.
What components define a system's form factor?
The power supply, the backplate, the spacing of the mounts for the motherboard, and the position of the expansion slots in relation to the CPU
