Question

Two parallel plate capacitors are constructed one by a pair of iron plates and the second by a pair of copper plates of same area and same spacing. Then –

• A. The copper plate capacitor has a greater capacitance the iron one
• B. Both the capacitors will have same capacitance only in uncharged state
• C. Both the capacitors will have equal capacitance only when they are equally charged
• D. Both the capacitors will always have same capacitance

Answer 1

Answer: (D)

Both the capacitors will always have same capacitance

Answer 2

Capacitance is independent of nature of plate material. It only depends on area and separation.
