5 Questions
Question 1 of 5
What is the primary purpose of earthing in an electrical system?
Earthing provides a low-resistance path to ground, enabling quick fault current flow for protection.
Question 2 of 5
Which of the following components is NOT typically connected to the earthing system?
Live conductors carry the power. Earthing connects non-current-carrying metallic parts for safety.
Question 3 of 5
What happens during an earth fault (also called a ground fault)?
An earth fault occurs when a live conductor makes unintended contact with the earth or a grounded part.
Question 4 of 5
What is the key advantage of a low earthing resistance?
Low resistance allows a larger fault current to flow, ensuring protective devices like circuit breakers operate quickly.
Question 5 of 5
Which type of earthing method typically involves burying a metallic plate deep into the ground?
Plate earthing uses a metallic plate buried vertically or horizontally in the earth for grounding.
