A capacitor is used in the 'back end' of a volt' xfmr to smooth out the ripple that occurs when changing from one voltage to another. Given the nature of a cap, it provides a slow rise & fall to fluctuating voltages, sort of like the struts on your car. It dampens the peaks & valleys.

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.
Can we use transformer as a generator?
No. Transformer essentially can step up or step down voltage or provide same voltage across the secondary side. It can not generate voltage on its own. Generator is essentially a rotating device. Transformer is a static device.
Can capacitor increase low voltage to high voltage?
yes a capacitor can improve voltage by improving power factor
What is the use of diodes in doubler voltage?
A: The purpose it to block the capacitor from discharging to the source
What is an electrical device that changes the voltage of electricity through the use of two sets of coils.?
The electrical device is a transformer.

What is the function of capacitor voltage transformer at the switch yard?
function of capacitive voltage transformer is measure high transmission voltage with low range voltmeter and oprate the relay circuit to oprate CBs.
How a capacitor steps down ac?
A capacitor doesn't step down AC voltage, that's what a transformer does! It really can't, no matter what the circumstances.
What function does a capacitor serve in an auto transformer?
An autotransformer does not normally use any capacitors as it is a transformer with one winding and the lower voltage is taken from a tap part-way up the winding. A capacitor could be added if there is a concern about the power factor presented by the autotransformer to the supply.
Can you use a high voltage capacitor on a low voltage battery?
Yes. You just don't want to exceed the voltage rating of the capacitor.
How do you establish no of turns in both high voltage and low voltage windings of a 3 phase transformer?
Through the use of the basic transformer voltage equation.
How you can choose the capacitor range for 24 volt output rectifier?
the high quality way is to rate the capacitor for: 2 times the DC voltage. or 2 times the peak voltage of the transformer. Consumer Industry does not care about prpoduct life span and accepts much less conservative "bare minimum" ratings to reduce cost: 1.5 times the DC voltage. or 10% higher than the peak voltage of the transformer A good 24V supply has a 35V capacitor. Of course the cheaply made product will fail sometime with such narrow margin.
What type of capacitor use to stabilize a 12 volt car when the voltage drops and how to wire?
"What type of capacitor use to stabilize a 12 volt car when the voltage drops and how to wire?"
Why use capacitors on fan motors?
capacitor stores charge ,so we use capacitor in fan for continuous voltage supply.
How is 11kv convert to 230v?
The higher voltage it transformed to a lower voltage by the use of a step down transformer.
What is the maximum DC voltage you could expect to obtain from a transformer with an 18V rms secondary using a full rectifier circuit with a filter capacitor?
25.46V assuming output of transformer is pure sinewave.
Why cant capacitor filter connected in series to load?
in output is pulsetting voltage remove the pulses to use the capacitor this passes the pure voltage to the load
