To investigate the relationship between current and potential difference (ohms law).
Ohm' Law
Aim: To investigate the relationship between current and potential difference (ohm's law).
Prediction: I predict that as the current increase or decrease the voltage will increase or decrease in the same proportion.
Safety: This is not a very dangerous experiment, never the less, we should take care when handling electricity and make sure that our hands are dry.
Apparatus:
- Power supple.
- Variable resistor
- Resistor
- Volt meter
