Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Different methods of earthing are used depending on soil condition, cost, and type of installation.
Step 1: Pipe earthing uses a galvanized iron pipe placed vertically in the ground.
Step 2: The pipe is surrounded by charcoal and salt to reduce earth resistance.
Step 3: Pipe earthing is simple, economical, and effective.
Step 4: Due to these advantages, pipe earthing is commonly used in domestic and small electrical installations. Therefore: \[ \boxed{\text{Pipe earthing}} \]
