Resistance Coil

In the physics lab at school, we often use resistance coils in various experiments to understand the behaviour of electric currents. One common experiment involves studying the relationship between the voltage across a resistor and the current passing through it, as described by Ohm’s law. By using different resistance coils and measuring the corresponding voltage and current, we can verify this fundamental principle of electricity.

Furthermore, they are also essential in demonstrating the concept of energy dissipation in the form of heat. By passing an electric current through a resistance coil and measuring the temperature change, we can illustrate how electrical energy is transformed into heat energy, which aligns with the principle of conservation of energy.

Additionally, they are integral in experiments related to series and parallel circuits. Students can observe how the total resistance changes when resistance coils are combined in different configurations within the circuits, providing valuable insight into the behaviour of electrical components in complex systems.

Overall, they play a crucial role in the physics lab. They provide practical demonstrations of fundamental principles and allow students to gain hands-on experience with electrical circuits and the behaviour of resistive elements.
