Product details

Resistance of wires - dependence on the length and cross-section

Item no.: P1372560

Principle

The resistance of a short thick wire is different to that of a long thin one.

Benefits

Flexible experimenting thanks to wireless data transmission
No additional cable connections between the building blocks needed - clear arranged and quick setup
Contact safety due to puzzle blocks system
Corrosion-free gold plated contacts
Doubled earning success: Electric circuit diagram on top, real components from below

Tasks

Examine how the value of the resistance of a wire depends on its length and cross-sectional area.
