Three capacitors having capanctances `20muF, 30muF` and `40muF` are conneceted in series with a 12V battary. Find the charge on each of the capacitors. How much work has been done by the battery in charging the capacitors?

Explanation

To solve the problem step by step, we will follow these instructions:

### Step 1: Determine the Equivalent Capacitance
For capacitors connected in series, the formula for the equivalent capacitance \( C \) is given by:

\[ \frac{1}{C} = \frac{1}{C_1} + \frac{1}{C_2} + \frac{1}{C_3} \]
