An electric shock may be caused by

• A. Poor insulation of wires.
• B. Touching the appliances with wet hands.
• C. No earthing of the appliance.
• D. All

Answer 1

The correct option is D All

An electric shock may be caused from an appliance due to
i) Poor insulation of wires,
ii) Touching the appliances with wet hands and
iii) No earthing of the appliance.
To avoid it,the insulation of wires must be of good quality and it should be checked from time to time particularly when they become old,so that no wire is left naked the appliance should never be operated(or touched)with wet hands and they should always be kept dry.the appliances must have its metallic case earthed the appliances must be provided with a fuse.

A person can get an electric shock by touching it if the wire has poor insulation of rubber over it.

An electric shock may also be caused by touching the appliance that was either not earthed or touching it with wet hands.

Thus option D is correct.
