Firstly, some may think that it’s a must, but no, it’s a choice. The aim is to transmit as much power as possible with minimal losses.
Electric power is a product of voltage and current (P=IV). It is also the product.of resistance and thesquare of the current (P=IxIxR).
.As you transmit electric power through wires, you will encounter wire resistance power losses.
The higher the current the higher the resistance power losses.It is therefore wiserto keep current as little as possible in order to avoid wire losses, but to make sure that you don’t reduce the power that you transmit, you did want to make your voltage higher.
