1. The problem statement, all variables and given/known data
you and your laboratory team have been given a project by your electrical engineering professor. Your team must design a network of capacitors that has an equivalent capacitance of 2 microF and breakdown voltage of 400V. The restriction is that your team must us only 2 microF capacitors that have individual breakdown voltage of 100V. Diagram the combination.

2. Relevant equations
Ceq = C1 + C2 + C3 + ... (for parallel)
1/Ceq = 1/C1 + 1/C2 + ... ( for series)

3. The attempt at a solution
I'm completely lost on how to start this problem. And another question, what is the breakdown voltage?

Re: Capacitance

Breakdown voltage is basically a limit on how much voltage you can put across a capacitor. If you have too much voltage, the capacitor "breaks down". Current passes through and the capacitor itself may be permanently damaged. You must design a circuit so that the total capacitance is 2μF, and no one capacitor exceeds 100 V as long as the total voltage across the circuit remains below 400 V.
