Solve both question.... It's objective type questions so as per bartlybe's guidelines you need solve both question.

20 What is countertorque a measure of? PRACTICAL APPLICATIONS ou are working as an electrician in a large steel manufacturing plant, and Y in the of doing preventive maintenance on a large DC you are generator. You have megged both the series and shunt field windings and found that each has over 10 M2 to ground. Your ohmmeter, however, indicates a resistance of 1.5 2 across terminals S, and S,. The ohmmeter indicates a resistance of 225 N between terminals F, and F2. Are these readings normal for this type machine, or is there a likely problem? Explain your answer. process

please solve each part thank you i will like

A 500 MVA synchronous machine has H, = 5.6 MJ/MVA and a 1200 MVA machine has H₂ = 2.0 MJ/MVA. The two machines operate in parallel in a power station. What is the equivalent. H constant for the two, relative to a 100 MVA base?
