A 340 V, 6 pole dc Shunt motor has the following parameters:
Rating: 35 kWCurrent: 122 ASpeed: 1000 rpmArmature resistance: 0.35 OhmSunt field resistance: 150 OhmFriction&Windage loss: 1.2 kW
What is the no load speed?
Suppose we have a linear function f(X). We are given two points on the line and their values: a, f (a), b, and f(b). Now we need to use linear interpolation to compute the value of a new point f(c).
A temperature transducer has the relationship R=200 + 10T where R is in ohms and T is in Celsius. The problem specifications are: Range is 30=T=50°C Resolution is 0.01°C Frequencies of interest are 0 to 100Hz Transducer dissipation constant is 20 mW..
The transfer function of a particular active low pass filter is G(s) = 200/[s(1+0.4s)(1+0.1s)]. a) At a frequency of 1.0Hz it is determined that the gain of this filter in dB b) Find the phase shift in degrees through the filter as the frequency appr..
A jet has 4 engines. Each engine gives a FAIL signal which is TRUE if the engine is broken, and is FALSE if the engine is working fine. The plane can fly as long as at most 1 engine is broken.
A voltage source V(t)=100cos(6Π109t - 45(degrees))(V) is connected to a series RLC circuit. If R = 10MΩ, C = 100pF, and L = 1H, use phasor notation to find the following: a.) i(t) b.) Vc(t) (voltage across capacitor)
A rectangular loop of wire containing a high resistance voltmeter has corners initially at (a/2, b/2, 0), (-a/2, b/2, 0), (-a/2, -b/2, 0) and (a/2,-b/2, 0). The loop begins to rotate about the x axis at constant angular velocity w.
(1) Explain what happens in a series circuit when the frequency makes Xc equal to XL. Does it have a name (2) What is the relationship between Ic and IL at Is minimum (3) Why is the source current, Is, minimum at certain frequency
Given the following IIR system with zero initial conditions: y[n]=0.2 x[n]- 0.5y[n-1] -0.06y[n-2] a)find the first five samples of the impulse response b) find the first five step response
a cost to produce, P, of $4.00. If we were able to reduce this to $3.55 through greater attention in the design, and if the cost to improve the design (in NRE) is $35,000, how many units must we sell to recover the increased design cost.
Design an inverting amplifier with a gain of -12 that has an input impedance that is larger than 100K that can drive a 2K resistive load using bipolar transistors. Verify your design analytically and with SPICE.
Consider the signal s = [ 1 4 6 7 -2 3] A. Determine the least-squares approximation s^ of based on v(1), v(2), and v(5). B. Compute the squared approximation error ||s^ - s||^2. C. Show that s^ = s when v(0), v(1), v(2), v(3), v(4), and v(5) are use..
Determine the net chage delta Q that flowed through a resistor over teh specified time interval for each of the following currents: (a) i(t) = 0.36A, from t=0 to t=3s (b) i(t) = [40t +8] mA, from t=1s to t=12s
