Q
What is potential difference ?
A
The cell or battery provides the push to make charges move. The push is called potential difference or p.d for short. The potential difference across a cell tells you about the size of the force on the charges. The potential difference also tells you how much energy can be transferred to the components in the circuit by the charges.
