Can Capacitors Charge Past Battery Voltage? Effects On Voltage
When a capacitor is connected to a battery, it will charge up to the battery''s voltage because the difference in potential drives the current into the capacitor. If a voltage higher than the battery''s voltage were to be applied, it could potentially damage the capacitor or create dangerous conditions.

Energy Stored on a Capacitor
The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor.The voltage V is proportional to the amount of charge which is already on the capacitor.

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 capacitor be charged by a battery?
In the diagram to the right a capacitor can be charged by the battery if the switch is moved to position A. It can then be discharged through a resistor by moving the switch to position B. lower plate and takes them from the upper plate. This leaves the lower plate negatively charged and the upper plate positively charged.
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.
How does charging a capacitor work?
The same ideas also apply to charging the capacitor. During charging electrons flow from the negative terminal of the power supply to one plate of the capacitor and from the other plate to the positive terminal of the power supply.
How does charge increase in a capacitor?
Charge The charge stored by the capacitor increases with every electron the moves to the negative plate. The amount of charge increases quickly at the beginning because a large current is flowing. As the current drops the rate at which the charge increases also drops. A maximum charge is reached. P.D.
When a capacitor is full of charge the current is highest?
The size of the current is always at a maximum immediately after the switch is closed in the charging or discharging circuit, because the charging current will be highest when the capacitor is empty of charge, and the discharging current will be highest when the capacitor is full of charge. This is shown in the graphs in Figure 2. 2.
