6 FAQs about [Capacitor potential and voltage difference]
How do you calculate potential difference across a capacitor?
To calculate the potential difference across a capacitor, you need to know the amount of charge stored on the capacitor and the capacitance of the capacitor. The amount of charge stored on a capacitor can be calculated by multiplying the voltage applied to the capacitor by the capacitance of the capacitor. $$Q = CV$$ where:
