The nameplate on a 50 kVA transformer shows a primary voltage of 480 V and a secondary voltage of 120 V. We wish to determine the approximate number of turns on the primary and secondary windings. Toward this end, three turns of wire are wound around the external winding, and a voltmeter is connected across this 3-turn coil. A voltage of 76 V is then applied to the 120 V winding, and the voltage across the 3-turn winding is found to be 0.93 V. How many turns are there on the 480 V and 120 V windings (approximately)?
A single-phase half-wave rectifier is fed with a triangular signal with period 2 . The maximum positive and negative amplitudes are ± 12 V rms. determine: a) The value of the DC output voltage. b) The percentage of curly
Consider a permanent-magnet dc motor with the following parameters: Ra=0.35Ω, La=1.5 mH, Ke=0.5 V/(rads/s), Kt= 0.5 Nm/A, and Jm= 0.02 Kg.M^2. The rated torque of this motor is 4Nm.
Although this forms PNP and NPN transistors, the bias of the regions is designed so the junctions are reverse biased and the electric field effects on the channel are supposed to control the MOS-FET transistor soperations.
The Problem: An Electric Heater is connected to a constant 250-V source and absorbs 1000 W. Subsequently, this heater is connected to a constant 210 V source.
