"Earth wire is a safety measure in domestic electric circuits." Justify this statement explaining its role in case of accidental leakage of electric appliances.
Marking-scheme solution
Earthing is used as a safety measure, especially for those appliances that have a metallic body which is connected to the earth wire.
It provides a low-resistance conducting path for the current.
-Thus, it ensures that any leakage of current to the metallic body of the appliance keeps its potential to that of the earth, and the user may not get a severe electric shock.All Magnetic Effects of Electric Current questions2024 question paperNCERT solutions: Magnetic Effects of Electric CurrentPractice Magnetic Effects of Electric Current →
