- Draw a generalized house wiring diagram. Label the different components of the diagram clearly.
- Why the core of a transformer is laminated instead of being a solid one ?
- Based on the structure of core and winding how transformers grouped ? Draw schematic representation of each class.
- Compare the field winding resistance value for a D.C shunt motor and a D.C series motor. Why the field resistance values are unequal in both the cases ? Explain.
- What are the different components of a D.C machine ? Draw a schematic representation of a D.C series motor.
