Answer:
23954216.8 W
Explanation:
Power loss = I²R where I current = 765 A
R = 0.248 Ω/km × 169 km
R = 41.912 Ω
Power loss due to resistive losses = 765 ² ×41.912 Ω = 23954216.8 W
Answer:
23954216.83 W
Explanation:
The formula of power dissipated due to resistive losses is
Pr = I²R ................... Equation 1
Where Pr = Power dissipated due to resistive losses, I = current, V = Voltage.
But,
R = βL............... Equation 2
Where β = resistance per length of the wire, L = Length of the wire.
Substitute equation 2 into equation 1
Pr = I²βL.......... Equation 3
Given: β = 0.248 Ω/km, I = 756 A, L = 169 km.
Substitute into equation 3
Pr = 756²(0.248)(169)
Pr = 23954216.83 W
