A) 19.2 W
B) 19.2kW
C) 19.2J
D) 12.2kW
Correct Answer: B
Solution :
Potential difference (drop) between two cities \[=150\,\times 8\,=1200\,\text{V}\] Average resistance of total wire = \[0.5\times 150\] \[=75\Omega \] Power loss \[P=\frac{{{V}^{2}}}{R}=\frac{1200\times 1200}{75}=19200W\] \[=19.2kW\]You need to login to perform this action.
