A transformer does not normally contain a capacitor. However, you might be thinking of a 'd.c. power supply', which consists of a transformer, rectifier, and smoothing circuits. The smoothing circuits will contain capacitors.

What is mov capacitor?
A capacitor used to protect the transformer if these any problem in the cct.
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.
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.
Does the capacitor coupling gives the higher gain in case of amplifier?
NO. Transformer coupling gives the higher gain in case of amplifer.
Why you are using the capacitor voltage transformer in Sub station?
To Step down high voltages we require CVT,because it will step down the volatge by uisng capacitor in its circuit.
What is mov capacitor?
A capacitor used to protect the transformer if these any problem in the cct.
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.
How do you reduce DC?
by using a resistor or capacitor or transformer
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.
Which coupling gives the higher gain in case of amplifier - a Capacitor coupling b Impedance coupling c Transformer coupling?
transformer coupling
How do you fix the run capacitor on a ceiling fan?
Be certain to observe the exact same polarity as the old one. A capacitor does have plus and minus leads. Should an old defective ceiling fan transformer be replaced by a capacitor?
How can you find out if your 12 volt transformer for halogen lighting is dimmable?
Look at it and find its weight. If it is heavy it contains a transformer and is dimmable. If it is very light and obviously contains no transformer, it can't be dimmed.
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.
What happens when current transformer is replaced by a capacitor?
You will end up with no current output on the secondary side of the CT.
Does DC amplifier exist?
Yes, it's called a Transformer. Definitely the wrong answer. DC on a transformer is certainly going to blow it up. The answer is yes unless capacitor coupling is involved
