Asked by Arielle
Transformers are used to increase the voltage produced at power plants. Why is it desirable for the power to be transmitted at high voltage?
(a) the the transformer induction will be less resulting in less joule heating
(b) then the resistance of the wires will be less resulting in less joule heating
(c) then the current will smaller resulting in less joule heating.
(d) then the speed of transmission will approach the speed of an EM wave (c).
