Question: What happens to the total capacitance when capacitors are connected in series?

Options:

1. It increases
2. It decreases
3. It remains the same
4. It becomes zero

Correct Answer: It decreases

Solution:

When capacitors are connected in series, the total capacitance decreases and is given by the formula 1/C_total = 1/C1 + 1/C2 + ... + 1/Cn.
