Question

1a) To get the greatest capacitance you can, you would want to have plates that are:

1b) Two capacitors have the same charge Q on them - which one will store more energy?

1c) An initially uncharged capacitor begins charging at t = 0. When is the current largest?

1d) You measure the current in an RC circuit and observe that it is exponentially decaying. You can conclude that the capacitor must:

1a) To get the greatest capacitance you can, you would want to have plates that are:

A) small and close together
B) large and far apart
C) small and far apart
D) large and close together

1b) Two capacitors have the same charge Q on them - which one will store more energy?

A) they will both store the same energy
B) cannot determine from information provided
C) the one with the smaller C
D) the one with the larger C

1c) An initially uncharged capacitor begins charging at t = 0. When is the current largest?

A) When it is halfway to being charged
B) When it first begins charging
C) The current is constant during the charging process
D) When it is nearly done charging

1d) You measure the current in an RC circuit and observe that it is exponentially decaying. You can conclude that the capacitor must:

A) this is not possible
B) charging or discharging
C) discharging
D) charging

Explanation / Answer

!a) C = e0 A / d

C will be greatest if A larger and d smaller

Ans. Large and close together

1b) E = Q^2 / 2C

E will be larger if C is smaller.

Ans. C) the one with the smaller C

1c) B) when is begins charging.

1d) D) Charging
