An ideal regulator would hold the thing it is regulating (e.g. voltage, current, water pressure, motor speed) absolutely constant, or in other words with zero variation of that parameter. The quality of regulation in actual regulators however can only approach this ideal of zero variation.

What is regulation of a transmission line?
Regulation has to do with keeping the voltage at a desired value. This is often put in a per unit value, which you can think of as a percent of nominal. So if the desired voltage is 34.5kV, and the actual voltage is 33.8kV, the voltage is .98 per unit. There are regional and national rules on how low or high voltage can be. If the voltage strayes from this, it must be regulated back to an acceptable value.
How the voltage regulation in 33kv line?
It does not depend on the line. The regulation is the percentage change in voltage caused by applying the full load current, and that depends on the transformer supplying the line. A value of 5% would be typical.
Why is it thatFET is called a voltage operated device?
since in an FET the value of the current depends upon the value of the voltage applied at the gate and drain...so it is known as voltage controlled device.. for example..in a mosfet..the current from drain to source depends upon the width of the depletion layer..which in turn depends upon the voltage applied on the gate.. so that is the reason
An ideal voltage source charges capacitor in?
A: A voltage source Will charge a capacitor to 63% of its input value, The value to get there is stated a Resistance time capacitor as time. Mathematically it will never get there but engineering consider 5 times RC time constant as close enough,
What is transient voltage?
A transient voltage is a time varying voltage value. Transient says that the voltage value changes, especially from a steady state, to a new value, then back again.
What is the ideal value of percent regulation?
The percentage of regulation is a measure of the variation of ac voltage as a function of dc output voltage. Perentage of regulation=(Vnl-Vfl)/Vfl *100% Vnl=vltge acrs load rstnce at min crnt Vfl=vltge acrs load rstnce at max crnt

An ideal voltage source will charge an ideal capacitor?
An ideal capacitor is characterized by a single constant value for its capacitance.
You want to know about the voltage selector circuit using transformer?
the voltage selector circuit is used for converting input electrical energy through the voltage selection circuit,which is arranged within the transformer body with its two ends electric allay connected to an input port and an output voltage connection device must be plugged in a socket portion on the transformer body to initalize a micro control unit through feedback to change a volatage value sent to a voltage transformer unit and in turn change the voltage of output electrical energy until a display device displays an ideal output voltage value. Then, the user removes the connection device, and the voltage value of the input electrical energy is converted into corresponding to the selected

What is voltage regulation?
Voltage regulation:(from point of view of electrical machines or generator): It is the change in voltage in between the full loaded and no loaded condition. When there are no loads connected the terminal voltage is equal to the generated voltage in the generator. But when load is connected the terminal voltage is found to be lass than the no loaded condition, due to armature resistance leakage reactance.This phenomena is expressed as, % reg=(Vnl-Vfl)/Vfl * 100%.Which is Voltage regulation. ************************************************************ An ideal voltage source has zero internal impedance. A practical one, even a good one, has internal impedance. With no load on the source, the terminal voltage will have a given value. Once a load current is drawn there will be a voltage drop across the source's internal impedance, and the terminal voltage will therefore drop. The higher the load current, the higher the voltage drop. A regulator circuit, added after the source, can counter the effect of the source's impedance and maintain an output voltage which is more constant than the source itself can achieve.
Is the RMS value of the power output of a device running on a certain AC voltage equivalent to the power output of a similar device if it was running on the same voltage but it was DC instead of AC?
Yes.

What is the importance of peak inverse voltage?
Peak inverse voltage of a device like diode gives the maximum value of voltage that it can withstand without being damaged when it is reverse biased.
What is a 1k?
It is a passive electrical device with a resistive value of 1000 ohms, used for limiting current or dropping voltage.

Basic construction of zener diode?
A zener diode has a heavily doped p-n junction allowing electrons to tunnel from the valence band of the p-type material to the conduction band of the n-type material, such that the reverse voltage is "clamped" to a known value, called the zener voltage.
