Question

As electricity leaves the power plant and the transformers close by, its voltage is significantly increased. What is the purpose of this?

A.
The voltage needs to be increased because it has to be distributed to many homes and businesses when it reaches its destination.
B.
It must be increased in order to overcome the resistance in the wires over long distances.
C.
It must be increased because the power plant cannot create than much voltage on its own.
D.
It would be too dangerous for the employees of a power plant to create that high voltage of electricity.

Answer 1

B

Step-by-step explanation:

The power losses in transmission lines are I^2 R

if you push the voltage very high the current, I , will be far less and then the I^2 R losses will be much less
