The open circuit terminal voltage versus the field current (open circuit characteristics) for a separately excited dc generator driven at 1000 rpm is given below: IF(A) 0 0.1 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8 2. Eg(V) 12 16 30 55 75 90 100 110 115 120 122 123 Assume the machine is connected as a shunt generator and driven at 100 rpm and has a field resistance of 10012, a. Use excel spreadsheet to draw the open circuit characteristics from the given data b. Determine the open circuit voltage and exciting current of the shunt generator c. Find the critical resistance with the help of the graph d. Find the resistance to induce 105V with the help of the O.C.C.
