1
Q
Permeability
A
The ability of a material to concentrate or conduct magnetic flux
2
Q
Do capacitors promote a change in voltage?
A
No they change current, current leads
3
Q

A
Lead at 90
5
Q
On shaded pole motor the start winding are small?
A
They don’t have start windings ;)
6
Q
Disadvantage of auto transformers
A
They don’t eliminate transient voltage
