Sketch the phasor diagrams for the following waveforms:v1 = 80sin(pi*t + 35°)v2 = 80sin(pi*t - 10°)(a) What is the phase difference between v1 and v2?(b) Determine which voltage leads and which lags.
Two bars of silicon, one n-type and one p-type, are uniformly doped so that ND(bar1) = NA(bar2) = 3.7x1016 cm-3. a) Without calculations: which bar will exhibit the larger resistivity and why
However, the pump requires 60 W of parasitic power to operate continuously. Is installation of the pump justified. Explain. At what value of parasitic power does the addition of the pump become unjustified.
An opera glass uses an objective and eyepiece with focal lengths of +12 cm and -4.0, respectively. Determine the length (lens separation) of the instrument and its magnifying power for a viewer whose eyes are focused (a) for infinity and (b) for a..
Which is the best alternative to buying a machine assuming an interest rate of 4% and a time span of 6 years. Compare using Present Values. A: Buy new machines for $25k. They earn $5k per year and their maintenance costs are $125 per year.
Machine A was purchased three years ago for $10,000 and had an estimated market value of $1,700 at the end of its 10-year life. Annual operating costs are $1,350. The machine will perform satisfactorily for the next seven years.
The mean and the variance of a binomial distribution with parameters n and theta are 12 and 3. Find the probabilities: a. (P X or equal 7).
The counter should increment on the rising edge of an input signal we'll call COUNT. Another input called CLEAR should have the effect of setting the counter to zero if CLEAR = 1 when COUNT is asserted.
Desired D.C. Output : 10 V Load Variation: 0.3 kilo-ohms - 10 kilo-ohms Ripple Factor: Less than 0.1% for 2 kilo-ohms load Load Regulation: Better than 3 mV for a 1 mA change in load current
Problem on complex power, An electric load operates at 240 volts. The load absorbs an average power of 8Kw at a lagging power factor of 0.8.
1. Express the Boolean function f(X,Y,Z) = XY + X(Y + Z) in sum of products form showing the sum all nonzero minterms. 2. Express the Boolean function f(A,B,C,D) = A(B + BC) + ACD in sum of products form showing the sum all nonzero minterms.
