Question

1. Two 50 Ω resistors are in series in a circuit with a 10 V battery. The change in voltage, in the direction of the current, across either resistor is ___ V. Hint: Can you see why the voltage drop in the direction of the current is negative?

2. A 40 μF capacitor and a 80 μF capacitor are in series in a circuit with a 10 V battery. The voltage drop, in the direction of the current, across the 40 μF capacitor is ___ V. Hint: Can you see why the voltage drop in the direction of the current is negative?

3. A 40 μF capacitor and a 100 Ω resistor are in series in a circuit with a 10 V battery. After a long time the capacitor is fully charged and there is no current. The voltage drop, in the direction of the original current, across the resistor is V. The voltage drop, in the direction of the original current, across the capacitor is V. Hint: Can you see why the voltage drop in the direction of the current is negative?
