Current Question (ID: 20606)

Question:
$\text{A bulb and a capacitor are connected in series across an AC supply.}$ $\text{A dielectric is then placed between the plates of the capacitor.}$ $\text{The glow of the bulb:}$
Options:
  • 1. $\text{remains same}$
  • 2. $\text{decrease}$
  • 3. $\text{increase}$
  • 4. $\text{becomes zero}$
Solution:
$\text{When a dielectric is placed between the plates of a capacitor,}$ $\text{the capacitance increases.}$ $\text{In an AC circuit, this causes the impedance to decrease,}$ $\text{leading to an increase in current.}$ $\text{Therefore, the glow of the bulb increases.}$
