Capacitors in series combination

Two identical capacitors each of capacitance \(C\) and breakdown voltage \(V\) are connected in series. The respective values of capacitance and the breakdown voltage of the combination will be
\(C, V\)
\(frac{C}{2}, 2V\)
\(C, 2V\)
\(2C, 2V\)

Solution:

In series, the equivalent capacitance is \(C_{text{eq}} = frac{C}{2}\). Since the voltage is shared equally between the two identical capacitors, the maximum safe voltage across the combination is \(2V\).
