In a closed circuit if two 5volt power supplier are
connected in parrel what is the current direction in tihs
circuit?
What is difference between earth leakage relay and restricted earth fault relay ?
why we use star connection in HT motor? and delta connection in LT motor
how would you come to know if a transformer is double wound or auto? note that there is no tag. you are given only a multimeter.
What effect does a very low impedance have on the Voltage regulation? On the short-circuit current?
how we can calculate earth fault current?
why we use four type of phase angle difference between pimary & secondry winding of a transformer & where we use them?
Whether power factor should be high or low? Why?
If i connect aload to phase taken from one transformer and neutral from another what will happen.
why only dc is given as excitation...why not ac???
1 hp is equal to how much watt?
What is the difference between Earth and Neutral?
what is meant by MCB and MCCB? and what its full form?
