Capacitor charging involves the process of storing electrical energy in a capacitor. When a capacitor is connected to a power source, such as a battery or a power supply, current flows into the capacitor, causing it to charge. The charging process is governed by the relationship between voltage, current, and capacitance.
All you need to charge a battery from a capacitor is to have more voltage charged on the capacitor than the voltage of the battery. The size will only affect how much time the capacitor will charge the battery.
Yes, capacitors can be charged using batteries or any other direct current (DC) power source. However, it’s essential to ensure that the voltage rating of the capacitor is not exceeded during charging. What happens if you overcharge a capacitor?
The capacitor will charge up. When the voltage on the capacitor has reached the same voltage as the battery, current is still flowing (because of the inductance). It turns out that the energy stored in the capacitor is exactly the same as the energy stored in the inductor.
The voltage is V = Q/C V = Q / C which is 10,000 volts or so again. Even if you could charge it this much, it would be pretty bad to connect it to a 1.5-volt battery. To summarize, the charging is only good if the voltage is close to 1.5 volts but capacitors have vastly variable voltage that depends on the stored energy and/or charge dramatically.
To summarize, the charging is only good if the voltage is close to 1.5 volts but capacitors have vastly variable voltage that depends on the stored energy and/or charge dramatically. Normal capacitors store much less energy than batteries because they don't change any chemistry i.e. no "burning".
