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.
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 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 capacitor charge a 1.5 volt battery?
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.
Does the electric field of a battery work if a capacitor is uncharged?
The electric field of battery doesn't do any work initially since the capacitor is uncharged in the beginning. I believe that later if battery adds more charge to the already present charge, it will have to apply force against the electric field of already deposited charges and thus do work in the process. Is my assumption correct?
Why do capacitors charge faster if they are connected in parallel?
Consider this. Many capacitors connected in parallel to an input line, those capacitors are in series connected to battery. Whenever we need to charge, we plug in adapter that charges the capacitors. Since all are in parallel, they charge soon, since being capacitors, can charge faster too.
