ZIMSEC O Level Combined Science Notes: Experiment: Ohm’s Law

• It gives the relationship between potential difference and current through a wire in a circuit
• According to the law:
• \text{potential difference}\propto\text{current}
• The current passing through a wire is proportional to the potential difference across its ends
• Provided the temperature remains constant
• An equation can thus be formed:
• constant\dfrac{\text{potential difference(V)}}{\text{current […]
