A capacitor and a resistor has no effect on the supply voltage; however, this particular load combination will cause the load current to lead the supply voltage by some angle termed the 'phase angle'.

When excessive voltage is applied to a capacitor it will break down What factor of the capacitor has the greatest effect on breakdown voltage?
The dielectric material between the plates.
What happens when a start capacitor fails?
An open circuit, by definition, has no continuity, therefore there is no current flow. A failed capacitor in an open circuit would have absolutely no effect.
What is the effect of shunt capacitor?
A shunt capacitor creates a low resistance path in a circuit so that electricity can pass around to another point. Shunt capacitors create shorts when they receive abnormally high amounts of voltage to correct series circuits.
What is collector bypass capacitor?
A: It is not a bypass it is a negative feedback to effect the input voltage, Bias is when a DC voltage is applied to insure proper operation
What is the effect on the voltage gain of the circuit if different frequency values were to be used?

Effect of shorting out the capacitor in a clamping circuit?
Any circuit using a capacitor will not work if the cap is short-circuited.

What effect does the series resistance of a capacitor used in a capacitor filter have on diode current and ripple voltage compared with an ideal capacitor of no resistance?
The effective resistance of the capacitor reduces the ripple current through the capacitor making it less effective in its function of smoothing the voltage. But if the capacitor filter is fed by a transformer and diodes, the resistance of the transformer exceeds that of the capacitor.
What is the effect of an RL circuit in half wave rectifier?
The effect of an RL circuit in half wave rectifier is that the voltage output wave forms for current and voltage will be modified .
What is the effect of shunt capacitor?
A shunt capacitor creates a low resistance path in a circuit so that electricity can pass around to another point. Shunt capacitors create shorts when they receive abnormally high amounts of voltage to correct series circuits.
What effect a capacitor has on a supply current on an inductive load?
it will improve the power factor... The angle between voltage and current will decrease depends on capacitor value.
What is collector bypass capacitor?
A: It is not a bypass it is a negative feedback to effect the input voltage, Bias is when a DC voltage is applied to insure proper operation
What happens if the capacitor in fluorescent tube becomes faulty?
There's no effect since the capacitor was already faulty i.e it was like not in the circuit. Install a healthy capacitor because it will improve the power factor of the fluorescent lamp circuit thus reducing energy wasted.
What is difference among resistor capacitor and inductor?
In an AC circuit through a resistor the voltage and current are said to be in phase. Ie on the oscilloscope in the sine wave as the voltage rises so does the current in tandem. Through an inductor an electromagnetic field is created in the coil which produces a back emf which acts against any change in voltage. This slows down any sharp change in voltage as when a circuit is energised. With an inductor the voltage and current are out of phase. The voltage is said to lead over the current. It is displaced by 90 degrees. It is ahead of the current by 90 degrees on the sine wave. Through a capacitor the current rises until it is fully charged and then no more current flows. An AC current is constantly changing direction at 50 Hz in the UK. Through a capacitor the current leads over the voltage by 90 degrees in the sine wave. A capacitor can balance out the effect of the inductor. The inductor decreases the power factor, the capacitor increases the power factor. With an inductor a circuit draws more current, with a capacitor the current draw decreases. P=IxVxPf. Where Pf is the power factor or power correction factor. Factories will have a big capacitor to correct the power factor for induction motors. This improves the electrical efficiency and lowers the electric bill!
What is the effect of value of filter capacitor on ripple voltage?
Ripples in electricity are usually defined as small, unwanted variations due to direct current. The effect of using a filter capacitor in this environment may vary, but usually has a smoothing effect on the ripple.
What is the effect on the voltage gain of the circuit if different frequency values were to be used?
