Question

For three capacitors of capacitance $2\mu \text{F}$, $4\mu \text{F}$, $8\mu \text{F}$ connected parallel to each other having applied voltages $20\text{V}$, $40\text{V}$, $60\text{V}$ respectively. Then the equivalent breakdown voltage of the combination is?

• A. $60\text{V}$
• B. $11.4\text{V}$
• C. $20\text{V}$
• D. $40\text{V}$

Answer 1

The correct option is C $20\text{V}$

When capacitors are connected in parallel, breakdown voltage of the system is equal to the least brekdown voltage of the capacitors. So, equivalent breakdown voltage is $20\text{V}$.

So option (b) is the correct answer.
