Concepts Of Physics MCQ Edition [Volume 2]PhysicsCapacitors
If two capacitors, each having capacitance C and breakdown voltage V , are joined in parallel, the capacitance and the breakdown voltage of the combination will be
Options
- A2C and 2V
- BC and 2V
- C2C and V
- DC and V
Correct answer
C. 2C and V
Step-by-step solution
When two capacitors of capacitance C are connected in parallel, the equivalent capacitance is the sum of their individual capacitances. C_ eq = C + C = 2C In a parallel combination, the potential difference across each capacitor is the same and is equal to the potential difference across the combination. Therefore, the maximum voltage that can be applied across the combination without breaking down either capacitor is equal to the breakdown voltage of the individual capacitors. Breakdown voltage of the combination
