Question 1
Distinguish between earthing and bonding in domestic electricity.
Worked Solution & Example Answer:Distinguish between earthing and bonding in domestic electricity. - Leaving Cert Physics - Question 1 - 2021
Step 1
Earthing
Answer
Earthing means providing a conducting path to the Earth. This is often done to ensure safety by allowing excess current to flow into the ground in case of a fault. The main purpose of earthing is to protect users from electrical shocks and to stabilize voltage levels in the electrical system.
Step 2
Bonding
Answer
Bonding means providing a conducting path between objects, which effectively joins them together. This is crucial to ensure that all metallic parts of an electrical installation are at the same potential, reducing the risk of electric shock and equipment damage due to potential differences.
