Answer / ekanadam

yes we can run three phase motor with single or two phase
with help of capacitor displacement phase midifiers it
modifies 1 or 2 phase to 3 three

Answer / sparta

yes, we can run the motor by using 1,or 2phase, for that we
have to used capacitor or inductor for any one phase to
convert two phase into three phase system

In 110V DC supply,if a closed circuit gets open, How can we identify the voltage which is measured after the resistor(4KOhm) which is open with negative.it shows 55V +ve when measured, also the actual positive source is 55V +ve .Because there is no voltage drop in open circuit. How can we identify whether this is the voltage which is series with the resistor or the DC source direct +ve.
