Potenial Difference Flashcards
What is potential difference?
The cell or battery provides the push to make charges move. The push is called potential difference, or p.d. for short.
A cell or battery has a potential difference it is designed to work at . What is this called?
This is called a rating.
What will happen if you connect together the positive ends of two cells with the same rating? What will the potential difference be?
The p.d. will be 0 because the cells would cancel each other out.
Do bulbs have ratings?
Yes, they do.
State the unit of potential difference
V E.g This bulb will work at a potential difference of 6V
The p.d. Tells you about the…
Size of the force in the charges
The energy transferred by the cell to the charges
The energy transferred by the charges to the components in the circuit.
