Question

Why capacitor block dc and allow ac ?

Answer 1

HELLO MATE 【◆◆◆◆◆】【●●●●●】-------

capacitor allows DC current to flow through it when it's charging or dis-charging. I.E. the voltage accross it changes.

It's the same case in AC. hence it allows AC current to flow through it. A frequently asked question is the max. charge stored in it during AC.

DC ammeter works on the principle that a current carrying loop placed in a magnetic field experiences a torque (galvanometer principle)

HOPE THIS HELP YOU..☺️☺️

Answer 2

Explanation:

For any flow, there must be potential difference.In case of battery or capacitor, due to initial potential difference between two terminals (+ of source and + of capacitor /Battery) current starts flowing from source to load.As the charge get accumulated in capacitor the potential difference get reduced and in turn ...

sir more explanation is given in my diagram also

thanks
