Circuit "ith capacitor (+math) Consider the circuit smwn in figure above. emf (ekctrolmtive R)rce; R)rce lectronxjtrice) source has internal restarwe. restors have restarwes RI 6, 00 Q and R2 = 4, 00 Q . The capacitor has capacitarre C = 9, 00 {IF. When the capacitor is fully charged, nugnitude of the charge on its plates Q 36,0 "C . a) Calculate the emf e. b) Use Kirchhoff s ruks to establh equatn charge q on the plates of the capacitor.
