An uncharged capacitor is connected in s...

An uncharged capacitor is connected in series with a resistor and a battery. The charging of the capacitor starts at t=0. The rate at which energy stored in the capacitor:-

Text Solution

Verified by Experts

The correct Answer is:
A

Rate of change of energy =V.I.
Initially `V_(c)=0` hence `V_(c)I_(e)=0`
finally `I_(c)=0` hence `V_(c)I_(c)=0`
`therefore` There will be a maxima of power between these two instants.
