V/I = R · Resistance and the ohm

What we will be able to do

📏

State and use Ohm's law

📈

Read the V and I graph

🧱

Explain resistance and the ohm

🔥

Name the factors that change resistance

“

At constant temperature, the current through a conductor is proportional to the potential difference across it.

The notes are free to read in full.

Presenter notes: Today we learn how potential difference, current and resistance are linked.
