Each coil of a double-layer wound, 16-pole, 144-slot, three-phase, Y-connected, synchronous generator has 10 turns. The rotor is driven at a speed of 375 rpm. The flux per pole is 25 mWb. Each phase winding is connected in two parallel paths.
Determine:
(a) the frequency of the induced emf,
(b) the phase voltage, and
(c) the line voltage.
The current density in a cylindrical conductor of radius R = 43.1 cm, varies as J(r) = J0r/R (in the region from zero to R), where J0 = 0.417 C/m2. a) Find the magnitude of the magnetic field at r = 21.55 cm.
in a given byte-addressable computer, memory location 10000Hto 9FFFFH are avaliable for user programs. the first location is 10000H and the last location is 9FFFFH. calculate the following: the total number of bytes available (in decimal)
Single-phase distribution line runs parallel to a ground line and is separated by 2m. During a short circuit, the distribution line experiences a current of 10,000A rms. Determine the magnitude of the separating force acting on a 1m section of the..
A 60-Hz, single-phase transmission line has a length of 80 miles. Its shunt conductance (G) is 3.4×10?11 S/mile, resistance (R) is 0.1 ?/mile, capacitance (C) is 16 pF/mile, and inductance (L) is 0.56 mH/mile 220 kV, 220 MVA with power factor
Two teams of workers assemble automobile engines at a manufacturing plant in Michigan. Quality control personnel inspect a random sample of the teams assemblies and judge each assembly to be acceptable or unacceptable.
