In my understanding, theoretically, when an uncharged capacitor is connected directly to a battery of, let''s say, 9 volts, instantly the capacitor will be charged and its voltage …
capacitor
That fact that the battery may also store that much energy does not mean that there is a capacitor equivalent to a battery. While an ideal battery maintains the voltage across its terminals until the stored energy is exhausted, …
8.3: Capacitors in Series and in Parallel
When this series combination is connected to a battery with voltage V, each of the capacitors acquires an identical charge Q. To explain, first note that the charge on the plate connected to …
Explainer: How batteries and capacitors differ
It needs a lot of energy in a very short time to make a bright flash of light. So instead of a battery, the circuit in a flash attachment uses a capacitor to store energy. That capacitor gets its energy from batteries in a …
Improve a car battery''s performance with capacitors
$begingroup$ 0.5*83*16.2² is the total energy stored - unfortunately this is erroneous as (a) the battery voltage (and hence the capacitor voltage) is more likely to be around 13V and (b) the capacitor voltage can only …

In theoretical terms your calculation is correct for an idealised battery (constant voltage throughout discharge, defined mAh capacity) and an idealised capacitor. In real world …
8.1 Capacitors and Capacitance
Figure 8.2 Both capacitors shown here were initially uncharged before being connected to a battery. They now have charges of + Q + Q and − Q − Q (respectively) on their plates. (a) A …
Capacitors in Series Calculator
Look at the first capacitor – as electrons move to the power source, one part of the capacitor becomes positively charged. In equilibrium, this value is +Q.The fundamental …

To find the voltage of the battery in part (a) of Question 3, use the relationship between charge, capacitance, and voltage given by .
8.4: Energy Stored in a Capacitor
When a charged capacitor is disconnected from a battery, its energy remains in the field in the space between its plates. ... At some instant, we connect it across a battery, giving it a …
Ultracapacitors and the Ultracapacitor Battery
The unit of capacitance is the coulomb/volt, which is also called the Farad (F) [named after M. Faraday] with one farad being defined as the capacitance of a capacitor, which requires a …
