8.1 Capacitors and Capacitance – University Physics Volume 2
Capacitors with different physical characteristics (such as shape and size of their plates) store different amounts of charge for the same applied voltage V across their plates. The capacitance C of a capacitor is defined as the ratio of the maximum charge Q that can be stored in a capacitor to the applied voltage V across its plates. ...

How much current does a capacitor draw when charging?
The current when charging a capacitor is not based on voltage (like with a resistive load); instead it''s based on the rate of change in voltage over time, or ΔV/Δt (or …
18.5 Capacitors and Dielectrics
The battery is initially at zero volts, so no charge is on the capacitor. Slide the battery slider up and down to change the battery voltage, and observe the charges that accumulate on the plates. Display the capacitance, top-plate charge, and stored energy as you

How to Charge a Capacitor
In this case, the capacitor charges up to 9 volts, since it''s connected to a 9-volt battery. Many of the times while charging a capacitor, a resistor is used in series with the capacitor and voltage source to decrease the amount of current that flows through the ...
Why does capacitance affect the charging time of a capacitor?
Increasing the area of a capacitor''s plates gives charge carriers more room to spread out -- and, hence, more charge can be stored per voltage, and the capacitance goes up. * This may just spawn the next layer down of "why" -- if you feel the need to go there, this is treated very well in innumerable physics courses and probably …
How does charge redistribute when a charged capacitor is connected to an uncharged capacitor?
Your answer is wrong in the sense that the charge will not be equally divided between the plates of the two capacitors. And the reason is that the capacitors have different capacitances. In this case you need to apply Kirchoff''s voltage rule to get the correct equation.
