Question

2.(A) A capacitor consisting of two parallel plates with direct between them is connected to a battery. As a result, the plates become charged. The battery is then disconnected with the lates insulated so no charge can escape, and the dielectric is then removed. How would each of the following change? The charge on the plates. Increase / Decrease / Remains the same The potential drop across the plates. Increase / Decrease / Remains the same The capacitance of the capacitor. Increase / Decrease / Remains the same 2.(B) A capacitor consisting of two parallel plates is connected to a battery. As a result, the plates become charged. Ifa dielectric is then inserted while the plates remain connected to the battery, how would each of the following change? The charge on the plates. Increase / Decrease / Remains the same The potential drop across the plates. Increase/Decrease / Remains the same The capacitance of the capacitor. Increase / Decrease / Remains the same 2.(C) A capacitor is charged by a battery. The battery is disconnected with the plates insulated so no charge escapes from the plates. The plates of the capacitor are pushed together with the plates insulated so no charge escapes, how do each of the following change? The charge on the plates. Increase / Decrease / Remains the same The potential drop across the plates. Increase / Decrease / Remains the same The capacitance of the capacitor. 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 apart. How do each of the following change? The charge on the plates. Increase / Decrease / Remains the same The potential drop across the plates. Increase / Decrease / Remains the same The capacitance of the capacitor. Increase / Decrease / Remains the same 3. For the circuit shown below, assume that C C, and answer the following questions.
