6 FAQs about [Capacitor voltage is equal to the road terminal voltage]
Can a capacitor charge a battery?
With just the capacitor, one resistor and a battery, then the capacitor will charge until the current stops flowing. Since V = IR, once the current is zero, the voltage across the resistor is zero. If there's no voltage across the resistor, then all the voltage must be across the capacitor. So the battery and capacitor voltages must be the same.
How does a capacitor work?
