A section of superconducting wire carries a Current of loo A and requires 100 L of liquid nitrogen per hour to keep it below its critical tern1 to be economically advantageous to use a superconducting wire, the cost of cooling the wire must be less than the cost of energy lost to l Assume that the cost of liquid nitrogen is $0.30 per liter, and that electric energy costs $0.10 per kWh. What is the resistance of a normal as...

A 3-phase 50Hz 2-pole 440V (L-L rms) induction motor drive has a rated speed of 2955 rpm and rated torque of 35 Nm. This motor drives a load with a torque characteristic that increases linearly with speed such that it equals the load torque at the rated speed. It draws a current of 2.1 A(rms) per phase at the rated voltage at a power factor of 0.81 (lagging). The stator resistance Rs = 2.0 ohms. At the rated operating speed,...
