oooops sorry, the exact question I have is: 1) Consider the circuit in fig. 1 a) Derive the expression for the time taken for the p.d., Vc, across the capacitor array to reach 80% of Vo in terms of C1, C2, R and Vo

Hi there, in this part of the question, the values of Vc and Vo aren't given so I'm not too sure where to go from there

I've been trying to answer the following equation but I just can't get my head around it! 'calculate the time taken 't' for the voltage over capacitor array (Vc) to reach 80% of Vo, in terms of Vo, R, C1 and C2 (caps are in parallel)' I know I need these two equations but I just don't...
