alleryEarthing of an electrical appliance:
AIncreases current to the appliance
BProvides a low-resistance path for fault current to ground
CReduces voltage available
DStores charge for later use
Answer & Solution
Correct answer: B. Provides a low-resistance path for fault current to ground
1. Earthing means connecting the metal body of an appliance to ground via a thick low-resistance wire.
2. If a live wire accidentally touches the body, current goes through the earth wire (low R) rather than through a person touching it.
3. This prevents electric shock and trips a fuse / MCB.
