## Homework Statement

If you were given an enclosed box, containing two 2000uF capacitors, which were either joined in series or in parallel, suggest, with a reason, how you would determine which way they were connected.

## Homework Equations

C = C1 + C2 in parallel

1/C = 1/C1 + 1/C2 in series

## The Attempt at a Solution

I have calculated (using above equations) that in series the total capacitance is 1000uF, and in parallel the total capacitance is is 4000uF.

Therefore in series the total capacitance is double one of the capacitors and in parallel the total capacitance is half one of the capacitors. So this is how I have answered the question.

Though I'm wondering if I should mention about the time constant and how it is affected for both series and parallel?

Thanks very much
