You know that all the appliances like fans, lights,
TV, computers etc. work on the principle of electricity.
The human body offers considerable resistance to electricity
when it is dry. However, wet skin allows transfer of
electric current into our body easily. Materials like
wood, glass, air and rubber also offer resistance to
electricity. Sometimes while using various electric
appliances just by putting fingers into the sockets,
we may get a jolt of electric shock.
When current passes through our body, it causes contraction
of the muscles. If the current is long enough and strong
enough, it may cause the heart to beat funnily, it may
destroy the muscles and even cause burns at the site
where we touched the electric point. Hence, the best
may to prevent electric shock is to wear rubber-soled
shoes or slippers while handling electric appliances.
Also if a person is struck to the electric source, do
not pull the person with bare hands but pull him with
help of a wooden rod.
