A series voltage regulator with constant-current limiting is shown in Figure 17-47. Determine the value of if the load current is to be limited to a maximum value of 250 mA. What power rating must have?
Gaussian random variable W is known to have P[W>4] = 1/2. Based on this information, (a) sketch its possible PDF. (b) Now also assume that Var[W] is very small. Refine your sketch in the first part taking into account this new information.
A 60-Hz, 220-V-rms source supplies power to a load consisting of a resistance in series with a capacitance. The real power is 2000W, and the apparent power is 2500VA. Determine the value of the resistance and the value of the capacitance.
Find the waveform for the voltage induced across a 200- mH coil if the current through the coil is as shown in given figure.
If a constant current load draws 1 nA from the capacitor, how long does it taketo completely discharge the capacitor. Draw the voltage of the capacitor as a function of timeduring this discharge process.
The two loads draw a total average power of 52,800 W at a power factor of 0.8 leading. One of them draws 40K VA at a power factor of 0.96 lagging. What is the power factor of the other load
A silicon p-n-p transistor has impurity concentrations of 5*10^18, 2*10^17, and 10^16 cm^-3, diffusion constants of minority carriers 52, 40, and 115 cm^2/s and minority lifetimes of 10^-8, 10^-7, and 10^-6 in the emitter
It has been proposed that by placing an appropriately selected resistor across the line at a distance dmax from the load, where dmax is the distance from the load of a voltage maximum. Show that the proposed approach is valid and find the value of th..
A system has transfer function H (z) = z/(10z-3) (i) find its steady state response to a single frequency input of ej5n; (ii) find the steady state response to an input of cos(5n) and sin(5n).
determine the frequency response and the magnitude response of the z tranfer function below. please show step to step how to get the result. D is a positive interger
Five metal strips, each 0.5 X 1.5-in. cross section, are bonded together to form the composite beam shown. The modulus of elasticity is 30 X 106 psi for the steel, 15 X 106 psi for the brass, and 10 X 106 psi for the aluminum. Knowing that the beam..
A) Convert the following Switch Algebra function into NOR-NOR implementation (Draw the logic and then convert it into NOR-NOR): F = W X + Y Z +W Y Z B) Convert the following Switch Algebra function into NAND-NAND implementation
Design a circuit which provides 20 dB of gain. The 3dB filter points should be 50 HZ and 50 KHZ. Use a bipolar power supply (+/- 9V). Your circuit should be able to provide a minimum of 5 Watts of output power.
