A load supplied by a 3-wire d.c. distribution system takes a current of 600 A on the +ve side and 480 A on the −ve side. The resistance of the outer conductor is 0·015 Ω and that of the middle wire is 0·03 Ω. Determine the voltage at the load end between each outer and middle wire. Supply voltage is 500/250 V

Q5 A 3-phase, 60 Hz, 500 V, delta connected motor develops mechanical output of 250 H.P., the power factor being 0·7 lagging (without capacitors) and motor efficiency 88%. A bank of series capacitors is connected in delta across the supply terminals. Two similar capacitors connected in series exist in each phase. Each of these capacitors is rated at 250 V, 800 µF. What is the new power factor of the motor after connecting the capacitor bank, also find out saving...

A long, straight wire carrying a current of 3.00 A moves with a constant speed v to the right. A 5-turn circular coil of diameter 1.25 cm, and resistance of 3.25 µΩ, lies stationary in the same plane as the straight wire. At some initial time, the wire is at a distance d = 19.5 cm from the center of the coil. 4.55 s later, the wire is at a distance 2d from the center of the coil. What is...
