CBSE Class 10 Answered

Electricity doubts clear!!!

Hi dear,

when electrons move down a wire in electricity, the atoms (or ions ) get in their way and cause resistance. the longer the wire, the more ions for the electrons to bump into on their path, and so, the greater the resistance.

Hope this helps.
