electrostatic-potential-and-capacitance Question 48
Question: Q. 23. In a parallel plate capacitor with air between the plates, each plate has an area of $6 \times 10^{-3} \mathrm{~m}^{2}$ and the separation between the plates is $3 \mathrm{~mm}$.
(i) Calculate the capacitance of the capacitor.
(ii) If this capacitor is connected to $100 \mathrm{~V}$ supply, what would be the charge on each plate?
(iii) How would charge on the plates be affected, if a $3 \mathrm{~mm}$ thick mica sheet of $\kappa=6$ is inserted between the plates while the voltage supply remains connected?
A [Foreign 2014]
(ii) What will be the charge stored in the capacitor, if the voltage applied had increased by $120 \mathrm{~V}$ ?
A [Delhi I, II, III 2013]
