Consider a lossless transmission line of characteristic impedance Zo = 50 ohms and a time-harmonic travelling wave of rms voltage Vio = 10V on it. the Wavelength along the line is λz = 1m. Find the magnitude and phase angle of the load reflection coefficient, the maxima and minima of the total voltage and of the current of the line and their locations, and the standing wave ratio of the line, and sketch the voltage and current standing wave patterns along the line if it is terminated in a purely resistive load of resistance (a) RL = 250Ω and (b) RL = 10Ω, respectively.
Design I/O wiring to control forward and reverse 12Vdc motor using PLC OMRON CJ1M. Consider that the forward movement of the motor will be controlled by a forward button and the reverse movement of the motor will be controlled by a reverse button
In a vessel with a volume 3 m3 you put 0.03 m3 of liquid water and 2.97 m3 of water vapor so that the pressure is 101.33 kPa. Then you heat the system until all liquid water just evaporates. What is the pressure and temperature in the vessel at th..
