The law which states that in an electric resistance the current flowing is proportional to the voltage and inversely proportional to the resistance.
This week, Year 11 Investigating Science students investigated the relationship between voltage, current and resistance. Using Ohm’s Law, the students conducted a series of experiments where:
- The relationship is determined by measuring the current, whilst the voltage remains constant and the resistance is varied.
- The relationship is determined by measuring current, keeping the resistance constant and varying the voltage.
- The relationship is determined by measuring the voltage, whilst keeping the current constant and changing the resistance.
This stimulating activity was an engaging way to explore concepts of electricity and gain an understanding of the basic relationships between voltage, current and resistance.
