When a DC voltage is applied the electrons will increase in
speed proportional to the strength of the electric field.
These speeds are on the order of millimeters per second. AC
voltages cause no net movement; the electrons "wiggle" back
and forth in response to the alternating electric field

why to use freewheeling diode ( diode in revers bias mode) across dc coil
I want to put this query to SENIOR & EXPERIENCED ELECTRICAL ENGINEERS. 1)I want to know about the control circuit diagrams for control panels. I found it difficult to understand. Is there ant booklet through which we can learn the circuit diagrams? 2)I want to learn about conduiting, laying cables, preparing cable schedules and various techniques which is the part of building infrastucture(construction field). I don't have any experience in this area. I have experience in control panels only. that's why i am not getting any opening in building infrastucture (construction field).Can I get the job in this field as Trainee Engineer? How to enter this field? I need job in PUNE
