Consider the battery-charging circuit shown in Figure, in which vs(t) = 20 sin(200 πt),R = 80Ω ,VB = 12V, and the diode is ideal.
a. Sketch the current i(t) to scale versus time.
b. Determine the average charging current for the battery. (Hint: The average current is the charge that flows through the battery in one cycle, divided by the period.)
A small generator produces 10 C of charge every ten seconds across a potential difference of 100V. What is its power generation in Watts
Maximum Likelihood to get the above parameters i.e. u0 and var. Now from these 999 points, I take one point out (lets call it i) and add a new point (lets call it j). What will the new mean and variance be?
The balanced 60Hz waveform sample that we must modulate is the point where t=4.4ms. The DC voltage from rail to rail is 300V. assume the q axis and a axis are in same direction. The use of mathCAD is recommended.
1.Given S-DOman transfer function H1(s)= 1/(s+2). What is the time response H1(t). 2. Given H2(s)= (2s+5)/(s^2 +3S+2), what is h2(t) 3. Calculate the data value and address location for the following 8-bits date: 01111011 Buss address 10110011
Design the circuit such that IDQ = 0.25 mA and VD = -2 V. The nominal transistor parameters are VTP = -1.2 V, K'p, = 35 μA/V2 and viL = 15. Sketch the load line and plot the Q-point.
A combined-cycle, natural-gas, power plant has an efficiency of 52%. Natural gas has an energy density of 55,340 kJ/kg and about 77% of the fuel is carbon. a. What is the heat rate of this plant expressed as kJ/kWh and Btu/kWh
Graded-index separate confinement double heterostructure (GRIN-SCH) InGaAs/GaAs lasers with various cavity lengths were tested in the lab. The 100m wide oxide strip lasers consists of two pairs of 10nm In0.2Ga0.8As quantum-well (QW).
An Emitter follower with a BJT biased at Ic = 1mA and having β = 100 is connected between a source with Rsig = 20kg and a load RL = 1kg. a) find Rin, vb/vsig, and v0/vsig. b) If the signal amplitude across the base-emitter junction is to be limitd t..
Two lenses of focal length f1 and f2, made from the same glass, are spaced by distance L. The effective focal length of the pair is related to refractive index n by f^(-1) = (n-1)a + (n-1)b - L((n-1)^2)ab
Consider the magnetic circuit shown in Figure. Assume that the reluctance of the iron is small enough so it can be neglected. The lengths of the air gaps are 0.1 cm, and the effective area of each gap is 20 cm2. Determine the total number of turns..
