PhysicsEasysingle choice

Two identical parallel plate capacitors are placed in series and connected to a constant voltage source of $V$ volt. If one of the capacitors is completely immersed in a liquid of dielectric constant $K$ , then the potential difference between the plates of the other capacitor will change to

Options:

Answer:

Solution:

In series combination, charge is same.

$V \propto \frac{1}{C}$

Now, $\frac{V_{2}}{V_{1}} = \frac{K C}{C} = \frac{K}{1}$

But $V_{1} + V_{2} = V$

or $\frac{V_{2}}{K} + V_{2} = V o r V_{2} = \frac{K}{K + 1} V$
