How does charge change as voltage changes

As 1 increases, so does the other (assuming capacitance is constant)

How can you think about potential energy in a capacitor

Like the force of attraction between the 2 plates of the capacitor

In what direction does the electric field point in a capacitor

From the positive to negative

Does current flow through capacitors

No, they are unable to jump between the gap between the plates

How does charge distribute in series circuits

Charge is equal between all elements

How does charge distribute between parallel circuits

The total charge of the circuit is the addition of all of the charges

How does voltage distribute in series circuits

The total voltage is the addition of the voltage between all element

How does voltage distribute in parallel circuits

The voltage is the same at every point

How would you solve for the charge of each capacitor in this circuit

You find the total charge for the circuit. Q=CV

Then you find the ratio between the capacitors to find how the charge is divided between them.

How do you find ratios when calculating charges

Say you have 3 and 9 farads. The ratios between them is 1:3. So in total there are 4 parts. So you divide by 4 and multiply by each ratio
