The resistor with the smaller resistance is resistor: Current, I 40 35 30 R1 25 20 15 R2 10 5 Voltage, V O 1 O both resistors have the same resistance 0 2Question 7 5 pts A parallel plate capacitor of capacitance C has plates of area A with separation d between them. When it is connected to a battery of voltage V, it has charge of magnitude Q on its plates. It is then disconnected from the battery and the plates are pulled apart to a separation 2d without discharging them. The magnitude of the charge on the plates and the potential difference between become: O none of the other answers is correct Question 8 5 pts A 20x10-6 F capacitor is charged to 200 V and then discharged through a 1.0x103 2 resistor. The amount of charge on the capacitor after 10x10-3 s is approximately: O 2.4 mc O 14 mc O 0.80 mC O none of the other answers is correct O 3.2 mc O 1.6 mcQuestion 9 5 pts The gure shows three identical lightbulbs connected to a battery having a constant voltage across its terminals. When the switch Sis closed, the brightness of bulb 1: 0 increases O stays the same O decreases O No answer text provided
