i think electronics means " eloctron - machanics"........
the flow of electrons is current which may be a.c. or d.c.
so i think electronics & electricals both r depends on the
electrons flow...........
but the range of flow of electrons {or range of current}
biff b/w electronics & electricals.

generally in LT and MV motors we are using 3.5Coresx16,25,35,50 etc cable for supply.although motors is earthed at two point and having all protection.then why we are using that 1/2 core for earthing the motors.while in HT cable we are using only 3core cable for motor supply.generally lt and mv motors are delta connected and ht motors having star connection.whethere it is having any relation with winding connection( star or delta).all motors i am talking about are dol only.can anybody solve my confusion.thanks...
