1. Discuss the 3 factors that affect the capacitance of a capacitor and how these factors change the capacitance.

2. Each plate of a capacitor stores a charge of magnitude 2 mC when a 250-V potential difference is applied. The capacitance is:

a. 5 F

b. 8 F

c. 12.5 F

d. 500 F

e. none of these

3.A 3-F and a 1-F capacitor are connected in series and a potential difference is applied across the combination. The 1-F capacitor has:

a. thrice the charge of the 3-F capacitor

b. one-third the charge of the 3-F capacitor

c. thrice the potential difference of the 3-F capacitor

d. one-third the potential difference of the 3-F capacitor

e. none of the above

4. A 3-F and a 1-F capacitor are connected in parallel and a potential difference is applied across the combination. The 3-F capacitor has:

a. thrice the charge of the 1-F capacitor

b. one-third the charge of the 1-F capacitor

c. thrice the potential difference of the 1-F capacitor

d. one-third the potential difference of the 1-F capacitor

e. none of the above

5. A parallel-plate capacitor has a capacitance of C. If the area of the plates is halved and the distance between the plates is doubled, what is the new capacitance?

6. Rank the capacitors from least to greatest capacitance.

The plate areas and plate separations of five parallel plate capacitors are capacitor 1: area 1110/2, separation do capacitor 2: area 2A0, separation do capacitor 3: area 2A0, separation dO/Z capacitor 4: area An separation 24:10 capacitor 5: area An, separation Lin/2
