A parallel plate capacitor is charged and then isolated. The effect of increasing the plate separation on charge, potential and capacitance respectively are
Topic: JEE PYQ
Answer: B. Full step-by-step solution below.
- Aincreases, decreases, decreases
- Bconstant, increases, decreases
- Cconstant, decreases, decreases
- Dconstant, decreases, increases.
Correct answer: B
Solution
(b) As the capacitor is isolated after charging, charge Q on it remains constant. Plate separation d increases, capacitance decreases as and hence, potential increases asMore Capacitance PYQs
