Understanding Capacitor Circuits: Comparing Charge Flow and Brightness

[sonetard]

Homework Statement

A capacitor is charged through two bulbs (Figure 2a) and then discharged through a single bulb (Figure 2b)

a. Show the appropriate rays on the bulbs in each circuit
b. Mark each of the following statements as True or False. If the statement is false edit/alter the statement so that it becomes true.

1. _More charge flows through the single bulb than through the two bulbs.
2. _Charge flows at a greater rate through the single bulb than through the two bulbs.
3. _The single bulb shines brighter than either bulb in the two-bulb circuit.
4. _The total resistance of the two bulbs is greater than that of a single bulb.
5. _A compass would show a larger deflection for Figure 2a than for 2b.

Homework Equations

If they have both have 1 bulb, and one is charging and one is discharging, would they have the same flow rate and brightness?

The Attempt at a Solution

a. I think the one with two bulbs will be dimmer than the one with one bulb because there is less resistance. So it will have 4 lines each while the one with one bulb will have 6.

b. 1) F, I think this is because there will be less charge without the battery there.
2) T, because the one with two bulbs had to pass through a resistor 2 times.
3) T, because there is only one bulb. (but i don't get how that works)
4) T
5) T, because there is a battery while the one that is discharging does not. (I'm thinking that there is going to be more charge in the battery than the capacitor)

"A capacitor is charged through two bulbs" means what? How are the two bulbs and the capacitor wired? Are the two bulbs in parallel or in series?

Perhaps you could attach the figures mentioned?
