PRACTICAL EXPERIMENT: Length vs resistance of a wire - SPM & IGCSE Physics - Physics Rox

[@ArkanDisi]

this was helpful thank you. but how can i do this experiment but with using a slide potentiometer?

[@PhysicsRoxz]

Using a slide potentiometer will be a different experiment studying different variables. The slide potentiometer is used to change the voltage or current of the circuit, but cannot be used to change the length of the wire. So it cannot be used in this particular circuit; it would be in a different type of circuit to investigate different variables.
