Problem

A power plant uses a transformer to raise the voltage from 11 kV11\,\text{kV} to 132 kV132\,\text{kV} before transmitting electrical energy through a line of fixed resistance. By what factor is the power loss due to the line resistance reduced after stepping up the voltage? a) 124\dfrac{1}{24} b) 1144\dfrac{1}{144} c) 112\dfrac{1}{12} d) 1121\dfrac{1}{121}
