Concepts Of Physics MCQ Edition [Volume 2]PhysicsCapacitors
A parallel-plate capacitor with a capacitance of 5 F is connected to a battery having an emf of 6 V . The separation between the plates is 2 mm . Determine the charge on the positive plate.
Options
- A60 C
- B30 C
- C15 C
- D1.2 C
Correct answer
B. 30 C
Step-by-step solution
The charge on a capacitor is given by the relation Q = CV . Given: Capacitance, C = 5 F Potential difference, V = 6 V Substituting the values: Q = 5 F 6 V = 30 C The separation between the plates ( d = 2 mm ) is not required for this calculation. The charge on the positive plate is 30 C .
