State two circumstances when one may get an electric shock from an electric gadget. What preventive measures must be provided with the gadget to avoid it?
Answer
An electric shock may be caused from an electrical gadget due to —
(a) poor insulation of wires,
(b) touching the appliance with wet hands.
To avoid such incidents —

(ii) The appliance should never be operated with wet hands.
