Answer to Question #65475 in Electric Circuits for Helen
A high-voltage power line carries a current of about 1000 A. The formula for resistance
in a conductor is linear, so over large distances the net resistance of the power line
can be large. If the power is generated at a station at a typical distance from a home
where the electricity is delivered, the resistance of the transmission line is 24.3 Ω. Using
this information, determine the power lost between the station and the home. If the
potential at the power station is 750 kV, what is the power at the station? Determine
the ratio of these two numbers.
