There are two printers and two I/O ports available in a system. Process A is using an I/O port and is waiting for a printer. Process B is using a printer. Process C is using a printer and is waiting for an I/O port. Process D is using an I/O port. A resource-allocation graph of this situation will show _________.
Three Single-Phase two-winding transformers, each rated 25 MVA, 38.1/3.81 kV, are connected to form a three-phase Wye-Delta bank with a balanced Y-connected resistive load of 0.6 ohms per phase on the low-voltage side.
determine the capacitance of a parallel-plate capacitor having plates 14cm by 30cm separated by 0.01mm. The dielectric has (epsilon)(r)=15
Steel surfaces can be hardened by carburization. During one such treatment at 1000°C, there is a drop in carbon concentration from 5 to 4 at% carbon between 1 and 2 mm from the surface of the steel. Estimate the flux of carbon atoms into the steel
calculate ratio of the area to volume for unit cube, a unit sphere inscribed inside the cube and as right cylinder inscribed inside the cube.
Electrons are liberated with zero velocity from the negative plate of a parallel plate capacitor, to which is applied a magnetic flux density B parallel to the plates. Prove that these electrons will not reach the positive plate.
Given the electric field E=4xux+2yuyV/m find the voltage between the points A(2,0) and B(0,2) integrating along: (a) straight line AB; (b) broken line AOB, where O(0,0).
A) If 220kV, 220 MVA with power factor 0.8 lagging is determined to be at the receiving end, calculate the voltage at the transmitting end. B) If 220kV, 220 MVA with power factor 0.8 lagging is determined to be at the receiving end
A pipe of inner radius 4 cm, outer radius 6 cm, and infinate length is centered on the z-axis. Charge is evenly distributed within the wall of the pipe in the amount of 16 coulombs per meter length.Find and Plot the electric feild density as a fun..
a three phase motor operates at 70% efficiency, out of a 60Hz 480V balanced system of voltages. the motor takes a line current of 70A at a lagging power factor 65%. if the motor is rotating at 3500 rpm, and neglecting fraction, what is the torque ..
Three loads are connected in parallel across a single-phase source voltage of 240 V (RMS). Load 1 absorbs 12 kW and 6.667 kVAR; Load 2 absorbs 4 kVA at 0.96PF leading; Load 3 absorbs 15 kW at unity power factor.
(Combinational versus Sequential Circuits) Which of the fol¬lowing contain circuits that are likely to be combinational and which contain sequential circuits? Explain your rationale.
A potentiometer is wired is wired to represent a rotational range of 0-180 degree. The potentiometer is supplied with a voltage of 15 VDC. What is the output voltage at 75 degree
