Question
A 200 tonne train experience wind resistance equivalent to 60 N/tonne. The
operating efficiency of the driving motors is 0.87 and the cost of electrical energy is 0.5
D/kWh. What is the cost of the energy required to make the train travel 1 Km. if the
train is supplied at a constant voltage of 1.5 kV and travels with a velocity of 80 km/h,
what is the supply current?
