How can a capacitor hold different voltages? : r/electronics
The amount of charge it can store is equal to the voltage times the capacitance (the farads). So if you attach a 1 volt battery to a 1 farad capacitor (which is a very large capacitor) you would store 1 coulomb of charge in the capacitor. Now if you measure the voltage of a 1 farad capacitor holding 1 coulomb of charge you will get 1 volt.

6 Frequently Asked Questions about “How long does a Farad capacitor battery last ”
Do farad capacitors take a lot of power?
In theory, yes.. yes they do. But really.. look again at the math! It takes roughly the same power to charge a cap as it does to drain it, meaning that the electrical load for charging that 1 farad capacitor from 12.8 volts to 14.8 takes a whopping 27.6 WATTS for 1 second WOW! a 10 farad cap would take 276 Watts. ( 276w/14.8v =~ 20 amps)
How long can a capacitor hold a charge?
Capacitors are designed to store a certain amount of electrical energy, and if they are charged to their maximum capacity, they will be unable to hold any additional charge. As a result, the amount of charge stored on a capacitor will ultimately determine how long it can hold its charge.
How many Watts Does a 1 farad capacitor supply?
(Drop from 12.8v-10.8 ) 23.6 watt-seconds. (Drop from 14.8-10.8 ) 51.2 watt-seconds. This means that if you added a 1 farad capacitor to this car audio system, the cap would supply a whopping 27.6 WATTS for 1 second before the batteries became the current source.
What is the charge time of a capacitor?
The charge time is the time it takes the capacitor to charge up to around 99%, reaching its charger's voltage (e.g., a battery). Practically the capacitor can never be 100% charged as the flowing current gets smaller and smaller while reaching full charge, resulting in an exponential curve.
Can a capacitor store a charge?
No, capacitors are designed to store a certain amount of electrical energy, and if they are charged to their maximum capacity, they will be unable to store any additional charge. As a result, capacitors have a limited ability to store charge. Can a capacitor lose the charge it has stored over time?
How many volts can a 1farad capacitor supply?
This is how many Watt-Seconds the 1farad capacitor can supply from 14.8 volts down to 0 volts. to figure out how much power would be supplied to the system, we calculate the difference in stored power across our voltage drop. 1 Farad capacitor: 14.8v = ~109.52 Joules. <- Vehicle charging voltage.
