These are known as current-voltage graphs or I–V graphs close I-V graphs A graph of current vs potential difference for a circuit component..

We'll talk about three big ideas: electric potential difference (voltage), electric current, and electric field. Yes, they are all related, and I will show you how with some water and an LED.

- OCR 21st Century Current-voltage graphs Electrical current depends on resistance and potential difference. Different electrical components have different characteristics.
