How would I go about upping the voltage from 12V to 300-400V for charging capacitors
And you want to play with Caps charged to a few hundred volts - been nice knowing you!JackL said:Could you elaborate some, my knowledge of circuits is pretty limited

berkeman said:As the others have said, you need to learn a bit more about electronics and safety, before you go messing with voltages above about 50-60V.

When a 12v battery is connected to a capacitor, the battery's positive terminal supplies electrons to one plate of the capacitor, while the negative terminal withdraws electrons from the other plate. This causes a buildup of charge on both plates, resulting in a charged capacitor.
Yes, a 12v battery can overcharge a capacitor if it is left connected for too long. Once the capacitor reaches its maximum capacity, any additional charge from the battery will cause it to overcharge and potentially damage it. It is important to monitor the charging process and disconnect the battery once the capacitor is fully charged.
The time it takes to charge a capacitor with a 12v battery depends on the capacitance of the capacitor and the current supplied by the battery. Generally, it takes a few seconds to a few minutes to fully charge a capacitor with a 12v battery. However, this can vary depending on the specific components being used.
If a 12v battery is connected to a capacitor with the wrong polarity, the capacitor will not charge and may even discharge. This can potentially damage the capacitor and other components in the circuit. It is important to always double check the polarity before connecting a battery to a capacitor.
Yes, it is generally safe to charge a capacitor with a 12v battery. However, caution should be taken to ensure the correct polarity is used and to avoid overcharging the capacitor. It is also important to use proper safety measures, such as wearing protective gear and working in a well-ventilated area, when handling and charging capacitors.
