Three -phase motor is connected to a three-phase power source that has an abc phase sequence. the first load is a wye-connected, three-phase motor withdrawing a line current of 20A at a 0.8 lagging power factor. the secound load is a single-phase load between lines a and b of the three-phase power line, determine the total current in each line.
a) Based on your decision create a sampled signal of the sum of the two sines, and plot the magnitude of the zero centered FFT with property frequency annotation. Did it work Check with the data tip tool.
Invesitagtion of Intermodulation through an amplifier, An amplifier is designed to handle frequencies around 9 GHz. The bandwidth of the amplifier is 2 GHz with a center frequency of 9 GHz
A permanent magnet dc motor is delivering zero torque when it runs at 1800 rev/min and has 50 V dc applied to its terminals. The armature resistance is 2.0 ohm. What current will the motor need in order to deliver a torque of 2.0 Nm
A full-wave bridge rectifier circuit with a 1-kohms load operates from a 120-V (rms) 60-Hz household supply through a 10-to-1 step-down transformer having a single secondary winding
Devise a system that will convert this temperature range into an 8-bit digital word with conversion from 00H to 01H at 200°C and from FEH to FFH at 350°C . An ADC is available with a 2.500-V internal reference. At 200°C a type K TC produces 8.13 m..
What is the total power density and total available current density between wavelength of 280 and 1240 nm for the AM0 and AM1.5 spectra. Assume each photon generates on electron-hole pair. You will need AM1.5 and AM1.0 spectra.
