  1. 1 5.Two identical capacitors, have the same capaci- tance C. One of them is charged to potential Vj and the other V2. The negative ends of the capacitors are connected together. When the positive ends are also connected, the decrease in energy of the combined system isLJEE 2O02 (scr), 3] 4 1 4 2 2 c) C(v 2 Ans.( When two capacitors joined together by Connecting positive plate to positive plate and negative plate to negative plate, then the loss of mechanical energy or heat produced or work done to drive the change is given byy ubstituting 12-c


  2. 37. Seven capacitors, each of capacitance 2 F, are to be connected in a configuration to obtain an HF. Which of the combinations shown in figure will achieve the (1990-2 marks1 10 effective capacitance of desired result? HHI b) HHHF d) Ans (a) In combination (a) eff2 22 5 10 eff 1O or c


  3. 30. A 2 F capacitor is charged as shown in figure. The percentage of its stored energy dissipated after the switch S is turned to position 2 is (2011) 2 a) 0% b) 20% c) 75 % d) 80% Ans 2 2 CIC loss of energy 1O 8 10 % loss 8 10


  4. 7.Two identical metal plates are given positive charges Q1 and Q2 (<Q1) respectively. If they are now brought close together to form a parallel plate capacitor with capacitance C, the potential difference between them is 1999-2 marks] a) CQ1+Q2)/(2C) c) Q1-Q2)/C Ans. b) (Q1+Q2)/C d) (Q1-Q2)/(2C) (d) The two identical metal plates set up fields with intensities E. and E2 as shown in the figure. 2EA +22 2 1-(Q1-Q2) di 2C
