Задача id12056

When a tram moves along a horizontal section of track at a certain speed, its engine consumes current I1=100 A. Engine efficiency h=0.9. When the tram moves down the inclined section of the track at the same speed, the motor does not consume current. How much current will the motor consume when the tram moves up the same section of the track at the same speed? When solving the problem, take into account that the efficiency of the motor depends on the current consumed.
