1. A 40 μF capacitor is connected in series with a 10 Ω resistor in a circuit supplied by a 24 V battery as shown in the figure.
The switch has been for a long time at the position a and then it is moved to position b. What is the potential difference between the plates of capacitor after 0.3 ms?
Correct Answer: A
2. A 60 μF capacitor is connected in series with a 20 Ω resistor in a circuit supplied by a 6V battery as shown in the figure.
The switch has been for a long time at the position b and then it is moved to position a. How much time does it take to the battery to charge the capacitor at 90% of its full capacity?
Correct Answer: B
3. How much charge is stored in the capacitor shown in the figure 0.3 ms after the switch is moved from the position b to position a?
Correct Answer: C
