is it ? are you sure ? but i know so many circuit where capacitor is connected with ac supply .

still , if u connected a capacitor to dc supply , then :

1. if it is in SERIES with the dc supply , it will block all the dc current as capacitor

provides infinite resistance to dc current .

application : where u want to block dc current.(simple high pass filter)

2. if it is in PARALLEL with the dc supply , it will not block dc current , but if any ac

current comes out from the supply , the ac current will go through the

capacitor , as capacitor provides small resistance to ac current.

application : a) where u want to block ac current.(simple low pass filter)

b) to filter the noise (ac components) of dc supply.

What happens if dc supply is connected to incomer of transformer?

If a DC supply is connected to the incomer of a transformer, you effectively have a short circuit, because the DC impedance of a transformer (actually, any inductor) is quite low. You will blow something.

What happens to the DC load voltage when the filter capacitor is changed?

When the filter capacitor in a DC power supply is changed, the load voltage can be affected based on the capacitor's value. Increasing the capacitance generally results in a smoother DC output voltage with reduced ripple, leading to a more stable load voltage. Conversely, decreasing the capacitance can increase voltage ripple and cause fluctuations in the load voltage, potentially affecting the performance of connected devices. It's essential to choose the appropriate capacitor size based on the specific load requirements and ripple tolerance.


What happens when a capacitor connected across a battery for a long time?

For a long time, The capacitor will be charged to the voltage of the DC battery, the positive side of the capacitor touching the positive terminal of the battery. Not much DC current will conduct, except for some tiny leakage current due to imperfection of the cap. The battery will be drained eventually.


Can a non polarized capacitor be connected to a direct current circuit?

Yes, you can connect a polarized capacitor to a direct current. Make sure you get your polarization is correct.A non polarized capacitor can be connected in a DC circuit as well. "Non Polarized" just means it does not matter which side of the capacitor is positive. If you attempt to connect a polarized capacitor in a DC circuit backwards, you will know when the capacitor explodes.


But in DC ciruit there is no current when capacitor is connected?

This is because when you introduce a capacitor, the circuit is no longer a DC circuit. If you're using a multimeter see if there is an AC setting to measure the current.


Can a DC series motor with speed control be connected on AC supply?

A dc series motor with speed control can be connected on ac supply because dc machines are totally reversible.


Why you using DC power supply for capacitor?
