answer problem #2 write your solution on any peace of paper thank youuuuyuuy

Problem Solving. Solve the following problems completely. Write your solution in a separate short bond paper.
BOX your final answer.
Problem 1. A 50-kW, 250-V short-shunt compound motor has the following data: R₂ = 0.06 2, R = 0.04 2 and
R₁ = 125 £2. Calculate the induced armature voltage at rated load and terminal voltage. Take 2 V as the total brush-
contact drop.
Problem 2. A 60-hp 230-volt shunt motor has a shunt-field resistance of 38.3 ohms and an armature resistance of
0.04 ohm. if the resistance in the starter is 0.66 ohm, calculate the current input to the motor at the instant it is started
(assume 3-volts brush drop)
