Question

Explain the importance of measuring the critical speed and critical resistance for a dc shunt generator​

Answer 1

Answer:

There are two points on a highway A and B. They are 100 km apart. An auto starts from A and another auto

starts from B simultaneously. If they travel in same direction, they meet in 8 hours, but if they travel towards

each other, they meet in 2 hours. Find the speed of two autos.

Answer 2

Explanation:

The critical speed is the maximum resistance of the circuit in which the shunt generator resistance become the critical field and produce the voltage when the critical filed of the resistance is high as compared to the field circuit resistance.
