Question

Choose the best combination of the following that describes the properties of a parallel plate capacitor.A. If the area of the plates is increased the capacitance increases.B. This is because more electrons can fit on the plates with the same force between them (the same potential is applied).C. When the area of the plates is increased the capacitance decreases.D. This is because less electrons can fit on the plates with the same force between them (the same potential is applied).E. If the separation between the plates is increased the capaciatnce also increases.F. This is because the electric field between the plates increases (same applied voltage).G. The capacitance decreses as the separation between the plates increases.H. This is because the electric field between the plates decreases (same applied voltage).I. None of the above is true. C, D A, B, C, D C, D, E, F A, B, G, H B, D I A 1.5V battery is connected to a 250 mu F capacitor. The charge stored on the capacitor is 375 Times 10^-6 C 1.67 Times 10^4C 27.5 Times 10^-6 C 6000C 47.5 Times 10^-6C For the circuit below, two capacitors of different capacitance are connected in series. Indicate whether the statement 'Both capacitors have the same amount of charge on their plates.' is TRUE or FALSE. True False For the circuit in Question 3 indicate whether the statement 'the voltages across both capacitors are the same.' is TRUE or FALSE. For the circuit in Question 3 indicate whether the statement 'the sum of the voltages on the two capacitors equals the voltage of the battery.' is TRUE or FALSE. True False

Explanation / Answer

1. A,B,G,H

2. Q = CV = 250 x 1.5 uC = 375 uC = 375 x 10-6 C

3. True. in series capacitors always carry equal charges.

4. False..... same votage only if C1 = C2 which is not in given case.

5. True using KVL.
