Power P is to be delivered to a device via transmission cables having resistance R_C. If V is the voltage across R and I the current through it, find the power wasted and how can it be reduced.

P (Power transmitted)=VI

H (Heat Loss)=I^{2}R

High current flowing through the devices will lead to higher Energy Loss (as heat), so power should be transmitted at a high voltage and low current.
