1. The problem statement, all variables and given/known data Link: http://s359.photobucket.com/albums/oo40/jsmith613/?action=view¤t=PD_Capacitor.png How is cell E3 calculated? 2. Relevant equations 3. The attempt at a solution now I know I can use Q=CV BUT another possible method is to say: Voltage-Capacitor + Voltage-resistor = 5V (voltage supply) V-capacitor: 5-(1.11*3) = 1.67 (the m and k powers of +3 and -3 cancel) But this gives the value in cell E2....why does this method not work for E3?
