A copper conductor has a dia of 0.06 in and it is 1200ft long. Assume that the current total (dc) carried is 50A.
Find the total resistance of the conductor.
What current density exists in it?
What is the dc voltage between the conductor ends?
How much power is dissapated in the wire?
A variant of the binary symmetric communication channel is called a binary erasure channel. The transmitter sends a ‘0' or ‘1,' but at the receiver there are three possibilities: a ‘0' or ‘1' or ‘undecided bit (called erasure)' rec..
A phase modulation is used to transmit the signal s(t) = 10cos(20*pi*t) + 5sin(10*pi*t). kp = 3 rad/volts and fc = 20MHz a) What is the instantaneous frequency of the signal b) Write down the expression of the transmitted signal.
If the machine is driven at a speed of 459rpm to act as a generator of real power, find the rotor current referred to the stator and the real and reactive power outputs of the induction machine.
Find the generalized fourier series coefficients corresponding to these basis signals for the signal x(t) = 0.5(t-1)^2 in the interval 0
In a step-down converter, consider all components to be ideal. Let v_0 = V_0 be held constant at 5 V by controlling the switch duty ratio D. Calculate the minimum inductance L required to keep the converter operation
Selecting a manufaturer from the us and observing wether its annual revenues are more than one billion or not when it is known that 30% of all manufacturers have annual revenues totaling more than one billion dollars.
Show that a linear dependent current source controlled by a voltage appearing across an element in parallel with the dependent source is equivalent to a resistor. Determine the value of the resistance in terms of the parameters of the dependent so..
The parameters of a certain transmission line operating at ω = 6×108 rad/s are L = 0.35μH/m, C = 40 pF/m, G = 75 μS/m, and R = 17 Ω/m => α=0.0943 Np/m, β=2.2467 rad/m, λ=2.7966 m, Z0 =93.623-j3.6368
Hooke's law describes a certain light spring of unstretched length 33.6 cm. When one end is attached to the top of a doorframe and a 7.31 kg object is hung from the other end, the length of the spring is 42.4 cm.
Complex Voltage = 10-j20. try to convert it to polar coordinate with my Ti 89 but I keep getting my answers in arc tan.
A pulse compression radar transmits rectangular chirp pulses with bandwidths of 500 MHz. What is the approximate slant-range resolution after Dolph-Chebyshev frequency weighting that results in 30-dB sidelobes
A particular inverting amplifier with nominal gain of -100 V/V uses an imperfect op amp in conjunction with 100-k ohm and 10-M ohm resistors. The output voltage is found to be +9.31 V when measured with the input open and +9.09 V with the input gro..
