2.(A) A capacitor consisting of two parallel plates is connected to a bathery. As a resul, the plates beeome charged I dielectric is then inserted while the plates remain e The charge on the plates. The potential drop across the plates The capacitance of the capacitor connected to the bamtery, how would ench of the follwing chang 2.48) A capacitor consiating of wo parallel plates with dicelectric between t them is connected to a battery. As . plates become charged dielectric is then removed. How would each of the fellowing change? The battery is then disconnected, with the plates insulated so no charge can escape, and the The charge on the plates The potential drop across the plates The capacitance of the capacitor. Increase / Decresse Remains the same Incresse Decrease (Remains the sac Increase ecread Remains the same 2.(C) A capacitor is charged by a battery. The battery is discennected with the plates insulated so no charge escapes from the plates. The plates of the capacitor are pushed apart with the plates insulated so no charge escapes, how do each of the following change? The charge on the plates The potential drop across the plates The capacitance of the capacitor Increase/ Decrease / Remains the same Increase /Decrease Remains the same Increase / Decrease/ Remains the same 2.(D) A capacitor is charged by a battery. While remaining connected to the battery, the plates of the capacitor are pushed together. How do each of the following change? The charge on the plates The potential drop across the plates The capacitance of the capacitor. Increase / Decrease / Remains the same Increase / Decrease Remains the same Increase / Decrease / Remains the same 3. For the circuit shown below, assume that C C and answer the following questions. (A) How is V, related to V,? Ci C2 (B) How is Q, related to Q? 4. For the circuit shown below, assume that C C and answer the following questions. (A) How is V, related to V2? C1 (B) How is Q, related to Q2? C2

Explanation / Answer

Ques No 3:

(3A) As C1 and C2 are connected in parallel V1=V2 . So option (iii) is correct.

(3B) As Q=CV and C1>C2 and V1=V2, Q1 > Q2 . Option (i) is the correct choice.

Ques No 4:

(4A) C1 and C2 are connected in series. So C1 and C2 will have the same charge. Q1=Q2 implies C1*V1 = C2*V2 . C1<C2. So, V1>V2. Option (i) is the correct choice.

(4B) from the explanation of ques no 4A Q1=Q2. Option (iii) is correct.
