Its distribution is via the transmission grid to the small scale users (Samantha, 2008). Electricity has several uses.
The first use of electricity was communication whereby the telegraphs, radios and the television had electric motors that were run using electric current. In today's world, electricity is used in almost 75% of the machines. In the rural households, this invention is used for lighting, TV, cooking and other minor consumptions such as computers and fans, in the urban areas; electricity is used in major industries to run machines and other household uses such as running electric products (Ian, 2007).
