COMEDK · Physics · 18. Capacitance
The space between the two plates of a parallel plate capacitor is fully filled with a conducting slab. Then the capacitance of the capacitor is :
- A Zero
- B Reduced to half of its original value
- C Infinite
- D Doubled
Answer & Solution
Correct Answer
(C) Infinite
Step-by-step Solution
Detailed explanation
The capacitance \(C\) of a parallel plate capacitor with plate area \(A\) and separation \(d\) is given by \(C = \dfrac{\epsilon_0 A}{d}\). When a conducting slab of thickness \(t\) is inserted between the plates, the new capacitance is given by…
