As in all electronics devices that obtain power from the AC electric system, a power supply converts the AC to the DC voltage(s) needed by the electronics in the device. Depending on the needs of the device this power supply may deliver a single DC voltage or as many as several dozen different DC voltages.

Why the graph of breakdown voltage is cheaper than knee voltage?

Break down voltages happens at low voltages (.6 for silicon & .3 for germanium), whereas knee voltages at higher voltages. That's why its cheaper.


Verification of kvl and voltage divider rule with answer conkulasion?

Kirchhoff's Voltage Law (KVL) states that the sum of the electrical potential differences (voltages) around any closed circuit loop must equal zero. To verify KVL, one can measure the voltages across each component in a loop and confirm that their sum equals the total supply voltage. The voltage divider rule, which states that the voltage across a resistor in a series circuit is a fraction of the total voltage based on the resistor's value relative to the total resistance, can be validated by calculating the expected voltages and measuring them. In conclusion, both KVL and the voltage divider rule can be experimentally verified, demonstrating the consistency of circuit analysis principles.


What component generates the high voltage necessary to make a spark in a vehicle?

The component that generates the high voltage necessary to make a spark in a vehicle is the ignition coil. It converts the low voltage from the battery into a much higher voltage, typically between 12,000 to 45,000 volts, which is needed to create a spark at the spark plug. This high voltage ignites the air-fuel mixture in the engine's combustion chamber, enabling the engine to run.


What is total voltage in 3phase supply when one of the phase becomes zero?

There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.


Why is low voltage circuits separated from higher voltages?

avoid crosstalksafety, a short between them could cause hazardous voltages where none are expectedprotect low voltage equipment from damageetc.

What are the significance of computer peripherals in computer system?

The different peripherals are designed so that one component may fit one slot but not another. This is due to the different voltages certain components require to function. There for if you plug a component into a lower voltage peripheral then it would not work and if you plug a component into a higher voltage peripheral then it poses a fire hazzard as to much voltage can cause over heating and component failure.


What is a function of a power supply in a computer?

It converts "line voltage" (where you plug the computer in) to various DC voltages that have been filtered and made more usable for the processor and other components.

How is the voltage of the power supply for a series circuit calculated?

The circuit by itself doesn't determine the voltage of the power supply. If there's some additional requirement that goes along with the circuit, such as "The current through the circuit must be XYZ amperes.", or "The voltage across the third component from the north end of the circuit shall be ABC volts,", then that requirement would dictate the power supply voltage. But in order to calculate it, you'd need the knowledge of every component in the series circuit.


How are lower voltages combined into higher voltages for transmission?

Low voltages are not 'combined into higher voltages' for transmission! The lower voltage (e.g. the voltage generated at a power station) is applied to the primary winding of a large power transformer, and the required higher transmission voltage then appears across the transformer's secondary winding. The magnitude of the secondary voltage is determined by the turns ratio of the transformer's windings.
