Question 2
When is the mechanical power developed by a d.c. motor maximum?
Question 3
The graph shown below represents which characteristic of a d.c. shunt generator?
Question 4
Neglecting all losses how is the developed torque (T) of a dc separately excited motor operating under constant terminal voltage, related to its output power (P)?
Question 5
