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.

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.

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.

4. The total capacitance of two capacitors in parallel if one has a capacitance of 400 μF and the other has a capacitance of 200 μF is ___ F
