Then she does it again with two more of the capacitors. Then the two resulting 200 F capacitors are connected in series to yield an equivalent capacitance of 100 F . Because of the symmetry of the solution, every capacitor in the combination has the same voltage across it, 29 0 . 0 V ab VV ∆=∆ = 24 5 . = 0 V ±² 16.37 (a) From ( ) QC , V ( ) 3 25 25.0 F 50.0 V 1.25 10 C 1.25 mC Q µµ == × = ( ) and 3 40.0 F 50.0 V 2.00 2.00 mC × = 40 Q (b) When the two capacitors are connected in parallel, the equivalent capacitance is
