Two magnetically-coupled coils are wrapped around a mutualnon-magnetic material. The coefficient of coupling betweenthe coils is 0.388. L1 has 500 turns and a value of 23.75mH while L2 has700 turns and a value of13.70mH. Find the permeance of P11 ,P12 , P22 , P21, in nano-Webersper amp.
A full wave rectified current has a peak value of 20 A and a period of 2ms. Assume the current is flowing in a 50 ohm resistance. Tabulate frequency, peak values and average powers of the first four nonzero compoents in the spectrum.
A d-c voltage Vo is applied att = 0 directly to the input terminals of a lossless air dielectric transmission line of length l. The line has a characteristice resistance Ro and is terminated in a load resistanceRL =2Ro.
On the right side, we have an inductor and a impedance 2+4i and another impedance 20
Calculate the amount of work done if the process is considered to be polytropic. Assume the temperature to be 273K and the value of k for the process to be 1.4. All losses are neglected.
A three phase motor draws 20kva at 0.7 lagging power factor from a 240 V source. Determine the kVAR rating of the capacitors to make the combined power factor 0.9 lagging and determine the line current before and after the capacitors are added.
For each one of the 3 frequency responses, H(f), in parts (a), (b), and (c) do the following: i. Obtain the system's impulse response, h(t). ii. Indicate if the system is BIBO stable or not, and state why. iii. Indicate if the system is causal or not..
Discuss how you can identify which resistances are in series and which ones are in parallel in a series-parallel circuit. How might this affect how you measure current and voltages in the circuit with a digital multimeter.
A continuous time system is described by y(t) = t tan(x(t)). The continuous time system is sampled every T seconds to obtain a discrete time system y[n]. determine the mathematical expression for y[n].
From a large lot of new tires, n tires are to be sampled by a potential buyer, and the number of defectives X is to be observed. If at least one defective is observed in the sample of n tires, the entire lot is to be rejected by the potential buye..
A 50V DC source is connected in series with a switch, an 8.2k ohm resistor, and a 0.01 microfarad capacitor. There is no initial charge on the capacitor and the switch is open. Determine both A & B The time at which the capacitor is fully charged
Your embedded systems application requires you to implant a sensor in each of the taxiways of the airport and connect the sensor wires at the base of the ATC tower. The worst case distance is two miles.
The wave function of a certain standing wave on a string fixed at both ends is y(x,t) = 0.30 sin(0.0025x)cos(300t) where y and x are in centimetres and t is in seconds. If the string is vibrating in its fifth harmonic, how long is it
