This physics tutorial takes you through some calculations of wire resistance. The resistance of a wire is proportional to its length. This means if you double the length, then its resistance will also double. • However, the resistance of a wire is INVERSELY proportional to its cross sectional area. This means that if you double the cross sectional area, then resistance will HALVE. • Subscribe for more physics tutorials: http://bit.ly/Subscribe-Physics-Ninja • Visit GCSEPhysicsNinja.com to learn more about electricity at https://gcsephysicsninja.com/lessons/...
