Power P is to be delivered to a device via transmission

Question:

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

Solution:

Power consumed by the transmission lines is given as P = i2Rc

Where Rc is the resistance of connecting cables

Power is given as P = VI

The transmission of power takes places either during low voltage and high current or during high voltage and low current.
