how can we rotate a single phase motor (without cap.)in
reverse direction?

Answer Posted / piyush yenkar

either change the terminal of 'main winding' or 'auxiliary winding' but not both.
To say directly that you can not start a 1phase motor without capacitor is ot right.We can go for 'shaded pole motor' .but the direction of shaded pole motor can not be reversed.

True or false question. 1.The fuse provide phase and neutral 2.power loss in electrical circuit can take place in (resistance or inductance or capacitance). 3.two phase system each phase has separated by a phase difference of (90 or 180 or 270 or 45). 4.3 phase balanced star connected load neutral current shall be (line current or phase current or zero or unity)
