Question { Vikram Ispat Industries, 2335 }

Why battery is always operate on dc supply?


Answer

Dc means single polarity supply, when dc supply is given battery is charged with positive polarity only and on application of loaddstorage energy in battery will discharge. tut if there is a.c. supply is given then after each half cycle polarity of supply get reverse it lead to maintain stored energy's in battery is zero.

Question { 3382 }

Why inductor short on dc and capacitor allow to flow ac?


Answer

1.inductor- R=2pieFL in which R is direcly proportional to frequency bt in case of DC f is zero so no resistance offered to DC current flow bt it will be infinite high frequency AC current.
2.capacitor- R=1/2pieFC in which R is inversely proportional to frequency. in case of DC F is zero do infinite R is offered to DC current flow, therefore it allows to flow only AC one.
