Chapter 7, Problem 7.20P
A solid conductor of circular cross section with a radius of 5 mm has a conductivity that varries with radius. The conductor is 20 m long, and there is a potential difference of 0.1 V dc between its two ends. Within the conductor, H=105p2a° A/m. (a) Find a as a function of p. (b) What is the resistance between the two ends?

- A3 φ, 10 kVA, 220 V, four-pole, 60 Hz, star-connected synchronous machine has negligible stator winding resistance and a synchronous reactance of 6 ohms per phase at rated terminal voltage. The machine is first operated as a generator in parallel with a 3φ, 220 V, 60 Hz power supply. (a) Determine the excitation voltage and the power angle when the machine is delivering rated kVA at 0.8 PF lagging. (b) If the field excitation current is now increased by 20 percent (without changing the prime mover power), find the stator current, power factor, and reactive kVA supplied by the machine.arrow_forwardHANDWRITTEN SOLUTION NOT USING CHATGPTarrow_forwardDon't use ai to answer I will report you answerarrow_forward
