Question

In given circuit, when a dielectric slab is introduce between the plates of the capacitor , intensity of bulb –

• A. Increases
• B. Decreases
• C. May increase or decrease
• D. Can't say

Answer 1

Answer: (A)

Increases

Answer 2

i = $\frac{V}{Z}$ = $\frac{V}{\sqrt{R^{2} + X_{c}^{2}}}$= $\frac{V}{\sqrt{R^{2} + (1/\omega C)^{2}}}$
