Find the current that flows in a silicon bar of 10-µm length having a 5-µm x 4-µm cross section and having free electron and hole densities of 105 / cm³ and 1015 / cm³, respectively, when a 1 V is applied end-to-end. Use µn = 1200 cm²/V·s and µp = 500 cm²/V·s.
Efficiency in a power transformer is 98.6% when loaded such that its core losses equal the copper losses. Calculate the per unit resistance of this transformer.
The purpose of this problem is to show you the connection between Fourier series and linear algebra. For simplicity, we will consider a finite basis. All questions will be referred to the following basis B = {1, sin(400t), cos(400t), sin(800t), cos..
Design a 16 bit x 16 bit combinatorial multiplier. Use a topology similar to the 4x4 multiplier.
how to evaluate power dissipated in the components of an RLC series circuit by using matlab software?
Design a UV flip-flop using a JK flip-flop and two logic gates. where the characteristic table for the UV flip flop is U V Q(t+1) 0 0 1 0 1 !Q(t) 1 0 Q(t) 1 1 Q(t)
Developing secret codes has interested people for centuries. A simple coding scheme can be developed by replacing each character in a text file by another character that is a fixed number of positions away in the collating sequence.
A shunt dc motor has RA = 0.1-ohm and VT = 440 V. For an output power of 16.1 hp, nm = 1,213 rpm and IA = 103 A. The field current remains constant. Find the the rotational power loss in hp.
A linear time-invariant system is described by the difference equation y[n]=x[n]+x[n-4] (a) Find its impulse response h[n]. (b) Find its system function H(z). (c) Plot the poles and zeros of H(z) in the z-plane.
y(t) + 0.2(dy(t)/dt) = x(t) a. Find y(t) if x(t) = 6(e^-2t)u(t) and y(0) = 3. b. In a. identify the zero-input and the zero initial condition part. c. In a, identify the systems-type and the input-type part.
The amount of three phase power to be delivered in kW is equal to the total number of letters in your name (first name +last name) and the single phase power is 10% of three phase power. Assume same power factor for both types of loads.
