Homework Statement
A 200m long copper wire, with cross section area of 1.5mm2, is connected with a 10Ω resistor in a series circuit, and the supply voltage is 50V.
Homework Equations
Find the power loss in the copper wire, when ρ=0.0175 Ωmm2/m
The Attempt at a Solution
R=*L/A
P=V2/R
P=502/(0.0175*(200/1.5))
P=1068.37 Watt.
