An electric power plant can produce electricity at a fixed power P, but the plant operator is free to choose the volt- age V at which it is produced. This electricity is carried as an electric current I through a transmission line (resistance R) from the plant to the user, where it provides the use with electric power P'. (a) Show that the reduction in power AP = P –- P' due to transmission losses is given by AP = P²R/V². (b) In order to reduce power losses during transmission, should the operator choose V to be as large or as small as possible?
