Question

Assertion : In series combination, charges on two capacitors are always equal. Reason : If charges are same, the total potential difference applied across two capacitors will be distributed in inverse ratio of capacities.

Answer 1

Explanation:

both assertion and reason are correct

Reason:

1. In series combination charge is constant

Answer 2

Assertion : In series combination, charges on two capacitors are always equal.

Reason : If charges are same, the total potential difference applied across two capacitors will be distributed in inverse ratio of capacities.

We know that, the formula for calculating the charge on a capacitor and is given by,

$q = CV$

$\Rightarrow V = \dfrac{q}{C}$

$\therefore V \propto \dfrac{1}{C}$

If q is same, then the velocity across the capacitor is inversely proportional to the capacitance of the capacitor.

Therefore, in series combination, the charges on two capacitors will have the same quantity if they are initially uncharged.

And  the total potential difference applied across two capacitors will be distributed in inverse ratio of capacities.

Hence, both the assertion and reason are true statements.
