Physics · Electrostatic Potential
हिन्दीGiven below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): When an isolated charged capacitor is connected to an identical uncharged capacitor, the total electrostatic energy stored in the two capacitors decreases by \( 50\% \). Reason (R): The total electric charge on the plates of the two capacitors decreases by \( 50\% \) during the sharing process. In the light of the above statements, choose the correct answer from the options given below:
View Answer & Solution
Correct answer · Option C
is true but (R) is false.
Explanation
Assertion is true: \( U_f = \frac{1}{2} U_i \), so \( 50\% \) energy is lost as heat/electromagnetic radiation during charge sharing. Reason is false: electric charge is strictly conserved by the conservation of charge; total charge remains \( Q \).
