Answer:
In terms of electron flow, "resistance" refers to the opposition that a material or device offers to the flow of electric current through it.
Step-by-step explanation:
When electrons flow through a conductor, they encounter resistance due to collisions with the atoms of the material, which cause them to lose energy and slow down. This resistance to electron flow causes a drop in voltage and generates heat, which is dissipated by the conductor.
Resistance is measured in ohms (Ω), and it is influenced by various factors such as the size, shape, and material of the conductor, as well as the temperature and the current flow. Materials that have a high resistance are known as insulators, while materials that have low resistance are known as conductors.
