A coil of 5000 turns is wound in the form of an air-cored torus with a square cross section. The inner diameter of the torus is 60 mm and the outer diameter is 100 mm. The coil current is 0.25 A. (a) Determine the maximum and a minimum values of the magnetic field intensity within the toroidal coil (b) Determine the magnetic flux within the torus (c) Determine the average flux densty across the torus and compare it with the flux density midway between the inner and outer edges of the coil
design and implement a C++ program to simulate a game of Blackjack between two to four players. Your program must incorporate a two-dimensional array to represent the suit and the value of each card dealt to a player,
A current element of length 1cm is located at (1m, 3m, 4m) in free space and carries a current of 20mA along ay. An infinitely long filamentary current of 12A along az passes through the coordinate origin (0,0).
Enclose the binary counter with parallel load of in a block diagram, showing all inputs and outputs. (a) Show the connections of four such blocks to produce a 16-bit counter with a parallel load. (b) Construct a binary counter that counts from 0 thro..
A square pulse train (i.e. square wave) with low and high voltage values of VL= 0 and VH= 2.9 volts is applied to a DC voltmeter. The voltage measured by the instrument is 0.2 volts. The same signal is applied to an 99 O resistor.
A coaxial line consists of inner and outer conductors made of copper and having radii of a = 0.65 mm and b = 2.75 mm. The space between the conductors is filled with polyethylene (er=2.25). Find the characteristic impedance Z0
1. What should the length of an antenna be if it is going tobe used to send data at 145.01MHz, assume a 1/4λmonopole antenna is used. 2. The impedance of an antenna was measured as z = 17 -j470Ω what does this mean
Design a circuit for control of lights. There are 3 inputs:Reset, start and clock. Three outputs: Red, Yellow, Green, whichare used to turn on the lights. Only one light can be on at anytime. Reset forces the circuit into a state in which the red ..

The sinusodial modulating wave m(t) = (Am)cos(2*pi*fm*t) is applied to a phase modulator with sensitivity kp. The unmodulated carrier wave has frequency fc and amplitude Ac. Determine the spectrum of the resulting phase-modulated wave
A first order allpass filter impulse is given by h(t)=-δ(t)+2e-tu(t) (a) Find the zero-state response of this filter for the input etu(t). (b) Sketch the input and the corresponding zero-state response.
A power amplifier has a gain of 20 dB and an input level of 2 volts. Assuming that the input and output impedances are the same, what is the voltage level at the amplifier output
A 30-km, 34.5-kV, 60-Hz three-phase line has a positive-sequence series impedance z = 0.19 + j0.34 ?/km. The load at the receiving end absorbs 10 MVA at 33 kV. Assuming a short line, calculate: (a) ABCD parameters,
