A shunt generator has a field resistance of 60 Ω. When the generator delivers 6 kW, the terminal voltage is 120 V, while the generated EMF is 133 V. Determine: a) The armature resistance and b) The generated EMF when the output is 2 kW at a terminal voltage of 135 V.

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
