If earthing is not proper, it can result in a number of problems. First, it can cause electrical shocks. This is because when there is an electrical current flowing through a conductor, it creates a magnetic field. If this field is not properly grounded, it can cause the current to jump to nearby objects, resulting in an electrical shock. Second, improper earthing can also cause fires. This is because when there is an electrical current flowing through a conductor, it creates heat. If this heat is not properly dissipated, it can build up and cause a fire. Finally, improper earthing can also cause equipment failure. This is because when there is an electrical current flowing through a conductor, it creates a magnetic field. If this field is not properly grounded, it can cause the current to jump to nearby objects, resulting in equipment failure.
