What is line charging in transmission?
Transmission Line Charging To initially charge the transmission line, the generator voltage stably controlled from 30% of the rated voltage to 110% of the rated voltage by using AVR. The change-over switch (43CH) for initial transmission line charging is mounted on the operator's desk in the main control room.This Voltage Changes are required because of the Stray capacitance effect at the charging and boosts the Voltage at the other end and the inductance of the line drops the Voltage soon after charging
Why current leads in capaciter?
Capacitors resist a change in voltage. It takes current to effect a voltage change, resulting in the current "leading" the voltage. Similarly, inductors resist a change in current. It takes voltage to effect a current change, resulting in the current "lagging" the voltage.
What is the effect of change in load resistance on output voltage?
No.
What can electric current produce?
Voltage. Or, if you prefer, electromotive force (emf). What creates voltage? Electromagnetic action. Electrochemical action. Piezoelectric effect. Photoelectric effect. Thermoelectric effect. Contact electrification (static electricity). What was left out? BREAKDOWN produce in a crystal

What is capacitive effect in antenna?
The capacitive effect is an element's opposition to a change in AC voltage. The resistor will develop a positively charged current at it flows through a capacitor. This will prevent a change in the initial voltage.
If current drop does it effect the voltage?
Generally, yes. It would depend on the device you are talking about. In a resistor a change in current will result in an instant change in voltage. Inductors and capacitors do not change instantaneously but will over time.
What is the definition of solar cells?
A solar cell, as we normally think of them, converts light (electromagnetic energy or radiation) into a voltage through the phenomenon of photoelectric effect. This voltage is used to drive electrical devices or is stored, usually in a battery bank.
Can a ignition switch short have an effect on the alternator charging the battery?
any short in the electrical system will have an effect on the charging system
What is charging current in transmission lines?
Any two conductors separated by an insulating medium constitutes a condenser or capacitor.In case of overhead transmission lines, two conductors form the two plates of the capacitor and the air between the conductors behaves as dielectric medium. Thus an overhead transmission line can be assumed to have capacitance between the conductors throughout the length of the line. The capacitance is uniformly distributed over the length of the line and may be considered as uniform series of condensers connected between the conductors.When an alternating voltage is applied across the transmission line it draws the leading current even when supplying no load. This leading current will be in quadrature with the applied voltage and is termed as charging current. It must be noted that charging current is due to the capacitive effect between the conductors of the line and does not depend on the load. The strength of the charging currents depends on the voltage of transmission, the capacitance of the line and frequency of the ac supply. It is given by the expressionSignificance of Charging currents:Capacitance effect (responsible for charging currents) of the short transmission lines are negligible. However they are significant in medium and long distance transmission lines.In long distance transmission lines, during light loaded conditions receiving end voltage will be higher than sending end voltage. This is because of the charging currents and capacitive effect of the line
What is the effect of surge arrester on increase the voltage in medium voltage circuits?
What is the effect of surge arrested on increase the voltage in medium voltage circuits?
Does current effect the resistance in an electric series circuit?
The resistance remains constant. The voltage would change, in accordance with Ohms' law, with a change in current.
