Question

A 2-mu f and a 1-mu F capacitor are connected in series and a potential difference is applied across the combination. The 2-mu F capacitor has: twice the charge of the 1-mu F capacitor half the charge of the 1-mu F capacitor twice the potential difference of the 1-mu F capacitor half the potential difference of the l-mu F capacitor none of the above The diagram shows six 6-mu F capacitors. The capacitance between points a and b is: 1 mu F 3 mu F 4 mu F 6 mu F 9 mu F A charged capacitor stores 10 C at 40 v. What is the value of its stored energy? 400 J 200 J 4 J 2.5 J 1.25 J

12) first 3 capacitors in series C(3) = 1/ ( 1/6 + 1/6 + 1/6 ) = 2.0 uF

Second 3 capacitors in series C(3') = 1/ ( 1/6 + 1/6 + 1/6 ) = 2.0 uF

Both C(3) and C(3') in parallel so

C(final ) =2 + 2 = 4 uF ===============ANSWER) OPTION C)
