An electrical power line, having a total resistance of 2 Ω, delivers 1 kW at 220 V. The efficiency of the transmission line is approximately :
Question
Solution 1
To find the efficiency of the transmission line, we first need to calculate the power loss in the transmission line and then subtract it from the total power to get the actual power delivered.
Step 1: Calculate the current in the line The power P delivered by the line is given by P = VI, where V i Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
