Question 97Electricity & Electronics - QMED

The correct answer is D) it is quadrupled. The reason for this is that the power loss in a power transmission line is proportional to the square of the current flowing through it. This is known as the "I^2R" (current squared times resistance) relationship, where I is the current and R is the resistance of the transmission line. When the current is doubled, the power loss quadruples (increases by a factor of 4) because the current term is squared in the power loss equation. The other options are incorrect because they do not accurately reflect the quadratic relationship between current and power loss in a transmission line.
