Potential Difference
Voltage: The potential difference is often called voltage. It''s like saying how much "push" the electric charges have to move. Just like you slide down the slide because of the height difference, electric charges move in a circuit because of the p.d. Measuring Voltage: We measure p.d in volts. We measure p.d in volts.

What Is the Potential Difference Across Each Capacitor?
Each capacitor in the series has a different potential difference, and the total potential difference is divided among them according to their capacitance values. On the other hand, when capacitors are connected in parallel, the potential difference across each capacitor is the same and equal to the applied voltage.
Basic Electronics
Basic Electronics - Capacitors - A Capacitor is a passive component that has the ability to store the energy in the form of potential difference between its plates. It resists a sudden change in voltage. The charge is stored in the form of potential difference between two plates, which form to be positive and negative depending upo
