In a parallel plate capacitor with air between the plates, each plate has an area of , and the distance between the plates is . The capacitance of the capacitor is:
1.
2.
3.
4.
1. | 2. | ||
3. | 4. |
The F capacitor is initially charged to V (i.e. V) while the F capacitor is uncharged. The switch is now closed. The final potential difference across the F capacitor will be:
1. V
2. V
3. V
4. V
Three capacitors connected in series have a capacitance of each. The potential difference across each capacitor if the combination is connected to a supply is:
1.
2.
3.
4.
