1. The problem statement, all variables and given/known data I have 3 pairs of resistors and capacitors, with each pair in parallel. These pairs are in series with another resistor and a voltage source. I have been asked to find the voltage across the resistor in the middle pair as a function of time, assuming that at time t=0 the voltage is switched on. 2. Relevant equations 3. The attempt at a solution I am not sure how to approach this. In all the books i have the only rc circuits analysed are of 1st degree. I think that i need to use thevenin's theorem. Thanks for any help.
