1. The problem statement, all variables and given/known data https://www.physicsforums.com/attachments/circuit-gif.64003/ Basically I am asked to find the equivalent capacitor. 2. Relevant equations C = q/v Conservation of energy. 3. The attempt at a solution I have read a lot about this topic and how if they were for example resistor and R4 * R3 = R1 * R5, the bridge doesn't go through it a current and I derived that. But I couldn't do the same with capacitors, however I found that this also happens with capacitors. In the question, The equation above applies ( replace R with C) So here is my question, Is there is a simple highschool derivation for this? and what if the wheatstone wasnt balanced how would I calculate it?
