The parallel combination of two air filled parallel plate...
The parallel combination of two air filled parallel plate capacitors of capacitance and is connected to a battery of voltage, When the capacitors are fully charged, the battery is removed and after that a dielectric material of dielectric constant is placed the two plates of the first capacitor. The new potential difference of the combined system is:
Options
- A\dfrac{\left(n + 1\right)V}{\left(K + n\right)}
- B
- C
- D
Correct answer
A. \dfrac{\left(n + 1\right)V}{\left(K + n\right)}
