GCSE Physics - Fuses and Earthing #23

The video discusses electrical surges, their causes, and potential dangers such as fires and electric shocks. It explains safety measures like fuses, circuit breakers, earthing, and double insulation. Fuses are simple and cheap but need replacement after a surge, while circuit breakers can be reset. Earthing provides a safe path for excess current, and double insulation prevents electric shocks by covering appliances in non-conductive material.

How does earthing help prevent electric shocks?

Describe the concept of double insulation in appliances.
