The effect of resistance on the rate of charging or discharging a capacitor?
If the resistance is in series with the capacitor, the charge/discharge time is extended.
What is the type of capacitance effect exhibited in P-N junction when it is reverse biased?
1. Transition capacitance 2. Diffusion capacitance 3. Space charge capacitance 4. Drift capacitance
What is the difference between capacitance and stray capacitance?
Capacitance is an ability to store an electric charge. "If we consider two same conductors as capacitor,the capacitance will be small even the conductors are close together for long time." this effect is called Stray Capacitance.
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 if capacitance in transmission line is high?
higher phase shift lower impedance
What is effect of internal capacitance of transistor and resistor on propagation delay?
Internal capacitance of transistor increases propagation delay.Because charging and discharging of these capacitors will take more time which is not favourable.So always try to select transistors with minimum capacitance.

What does it mean to precondition batteries?
By fully charging and fully discharging some batteries the expected charge time can be increased. Some rechargable batteries will last longer per charge if they are fully discharged before you recharge them again. Recharging batteries before they are fully discharged may cause a battery memory effect that will allow the battery to run for a shorter period between recharges.
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

Does the stray capacitance or the resistance of the monitor cable have the greater effect on the monitor's color?
no
How does the Switching diode used in television tuning?
A: Those diodes are used as a variable capacitance whereby applying a voltage changes the capacitance which effect the frequency of the tuning circuit
