in the last problem of this lecture we got the Ke for 4000 rpm for the load which the motor runs at 4000rpm .my problem is how to apply the same constant value for Ke which is the constant for 4000rpm to 2000rpm running load,well my mind say well two different weights and motor needs more current for 2000rpm runnig load so that the voltage get reduced and current get increased.I thought there must have been twice the current for 2000rpm in comparison to the 4000rpm load.yes it's constant for 4000 rpm but how come for 2000 rpm such question sir please help me

[@obli8984]

we have to calculate the voltage again?
