GCSE Physics - Static Electricity #24

The video explains the concept of charge in materials, highlighting that all materials contain positive protons and negative electrons, which usually cancel each other out. When materials are rubbed together, friction can cause electrons to transfer, leading to static charges. Conductors allow electrons to flow back, preventing charge buildup, while insulators retain the charge. The video provides examples of static charge with different materials and explains how potential differences can lead to sparks. It also discusses how conductors like cars can accumulate charge, resulting in electric shocks.
