Transport of electrical energy
Study of the resistance of a conductor
Measuring the resistance of a wire
Transport and storage of energy
This device is composed of a heat resistant metal stand on which are fixed 9 conductive wires 50cm in length connected to banana safety sockets.
Four pairs of wires of identical diameter but of different natures make it possible to study the influence of the nature of the conductor or the length of the wire on the value of the electrical resistance.
A ninth wire of different diameter shows you the influence of the section of the wire on the value of the resistance.
