what's the full question mate?

Answer 2

Answer:

Step-How can we actually reduce the power losses in the wire which are given by i2r and v2/r ( correct me if i m wrong ) .They say increase the resistance , resulting lower current and there you go , i2r would be lower .But p=VI says that u will have to increase the voltage if u want the delivered power to be same .Say we increase V for that ,, bt if the equation
