What is the formula used to calculate line loss in electrical systems?

The formula used to calculate line loss in electrical systems is based on the power loss due to the resistance of the conductor when current flows through it. Option D, which is expressed as 2K x I x L, accurately represents the calculation of power loss in a transmission line.

In this formula:

• 2K represents a constant that includes the resistance of the wire and temperature coefficients related to the material.

• I is the current flowing through the circuit.

• L is the length of the conductor.

The product of these terms gives a measure of line losses incurred by the flow of current over a given distance in the conductor, typically expressed in watts. This formula is derived from the principles of electrical resistance and Ohm's Law, which state that power loss (or heat generated) in a conductor is directly proportional to the square of the current multiplied by the resistance.

Understanding this formula is essential for electrical engineers and technicians when designing systems to minimize losses, which can enhance efficiency and reduce energy costs.
