Why is electric power transmitted at high voltages?

Answer 1

We are aware that the amount of electric power lost due to Joule's effect is given by,

#P = I^2Rt#, thus in order to minimize the power loss, the current is supplied under very high voltage and as a consequence of law of conservation of energy, the current is reduced and substantially heat loss is also reduced.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
