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 […]
