6 FAQs about [Capacitor charging battery to do work]
How do you charge a battery from a capacitor?
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.
How does a battery work on a capacitor?

Why do capacitors charge faster?
Since all are in parallel, they charge soon, since being capacitors, can charge faster too. All these capacitors can be connected to a battery in series, so one capacitor when gets depleted, the charge flows from the next capacitor, the capacitor nearest to the battery is fully charged and keeps charging the battery slowly. Will this work??
Can a battery be connected in series with a capacitor?
Ps: the idea is to make fast charging work by using capacitors to hold temporary charge and use it to charge the battery. So battery can be connected in series with capacitors to achieve this? no, because to harvest the energy in the cap you have to lower the voltage below what the battery needs to charge.
Why does a capacitor take a long time to charge?
The reason it now takes time, is that when the capacitor charges, the voltage across the resistors decreases, so the current decreases as well, so the voltage on the capacitor will increase more slowly, and so on and so on, so it will actually approach the battery voltage slower and slower.
How does a capacitor store energy?
The voltage on the capacitor is proportional to the charge Storing energy on the capacitor involves doing work to transport charge from one plate of the capacitor to the other against the electrical forces. As the charge builds up in the charging process, each successive element of charge dq requires more work to force it onto the positive plate.
