What is over frequency?
when the current increases in voltages.
Graph of resistance of filament lamp against potential difference?
As potential difference increases in a filament lamp, resistance also increases due to an increase in temperature. The relationship between resistance and potential difference in a filament lamp is non-linear due to the temperature-dependent nature of resistance in the filament material. At low voltages, the resistance is relatively low, but as the temperature of the filament increases with higher voltages, the resistance also increases.
If the excitation of generator changes what happens to the terminal voltage?
By Decreasing the excitation voltage the terminal voltage will decrease and similarly by increasing the excitation voltages the terminal voltage will also increases.
What are the voltages in secondary transmission electric lines?
A: Those voltages are called distribution voltages to differentiate from transmission voltages. And that varies from state to state and locals . Usually around 10kv to 20 kv
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.
Cell phone battery voltages?
Cell phone voltages are DC5V-5.5V
What are signals composed of pulses of precise positive voltages and zero voltages?
Digital
Electric power is transferred over large distances at very high voltages Explain how the high voltage reduces power losses in transmission lines?
The conductor used to transmit power has a specific resistance at the given power frequency. Power transmitted is equivalent to I^2 * R, so as the current increases, the power loss from the conductor also increases. To maximize efficiency, power is converted to very high voltages, which decreases the current, which minimizes the power lost in transmission.AnswerThe primary reason for using high voltage transmission lines is because, for a given load, the higher the voltage, the lower the load current. Low voltages would require cables of enormous cross-sectional area making transmission impossible, whereas high voltages allow the use of manageable-sized conductors. A secondary reason is the corresponding reduction in line losses -as described above.
What are the standard voltages for transmission?
The standard voltage for transmission is about 115 to 1,200 kV (long-distance transmission). The extreme high voltages are measured more than 2,000 kV and it is exists between conductor and ground.Answer for UKThe standard transmission voltages in the UK are 400 kV and 275 kV. Primary distribution voltages are 132 kV and 33 kV, and secondary distribution voltages are 11 kV and 400 V. These are all line voltages -i.e. voltages measured between line conductors.
Why are transmission voltages in multiples of 11?
Transmission voltages are in multiples of 11 to allow for 10% transmission line losses. Therefore, to obtain 100% efficiency, voltages in multiples of 11 are transmitted.
What two voltages are present on a peripheral power connector?

If you have to add two alternating voltages how to add them?
A: Alternating voltages means the phase factor must be considered.
