Decreasing the field current in a shunt motor will
- decrease speed and increase torque.
- increase speed and increase torque.
- increase speed and decrease torque.
why
Flux losses in a transformer can be prevented by
- winding the primary on top of the secondary.
- the use of primary shielding.
- laminating the core.
How about 'laminating the core' ?
How would you find the direction of the electron flow in an armature located in a magnetic field?
- Flemings left hand rule.
- Flemings right hand rule.
- Maxwells corkscrew rule.
The question asks 'Fleming's right hand rule', because the direction of the electron is it. If the question wants 'Fleming's left hand rule' as an answer, then not 'the direction of the electron flow', but 'the direction of the motion' is suitable.
