Ohm's Law
Key Stage 4
Meaning
Ohm's Law states that "The current through a resistor at constant temperature is directly proportional to the potential difference across the resistor.
About Ohm's Law
- Ohm's Law only applies to conductors at a constant temperature.
- Ohm's Law only works at low current because current has a heating effect on a conductor.
- An ideal resistor follows Ohm's Law.
