A network has a 5 μF capacitance in series with the parallel combination of a 12 μF capacitance and a 8 μF capacitance. Sketch the circuit diagram and determine the equivalent capacitance of the combination.
he storage capacitor in each cell has a capacitance of 50 fF and is fully charged to 5V. Find the worst-case leakage current (i.e. during the refresh cycle 50% of the stored charge is lost) that the dynamic node can tolerate.
A 600V, dc shunt motor has an armature and field resistance of 1.5 ohm and 600 ohm, respectively. When the motor runs unloaded, the line current is 3A, and the speed is 1000 rpm.
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.
Make a plot of group velocity versus frequency for frequencies from 0 Hz to 500 kHz. Your plot should have 3 different curves for the three modes of propagation. Be sure to identify the modes and all cutoff and resonant frequencies clearly.
Construct an inverting Dc integrator circuit using a jumperwire to act as the switch across the feedback capacitor. Notice that the input voltage is 0 V, so the output voltage shouldnot change, even after the switch is opened.
The equation y[n] - p y[n-1] = x[n] can be used to describe the value y[n] of a new investment by setting p = 1 + r/100 where r is the interest rate per period, expressed in percent.
You have a computer with a 1 GHz processor (that executes each instruction in one clock cycle) and a memory system that always takes 50ns to access one word. How long does it take to execute the instruction a = b + c
An accelerating voltage of 2.45 *10^3 V is applied to an electron gun, producing a beam of electrons originally traveling horizontally north in vacuum toward the center of a viewing screen 35.3 cm away.
A 100μF capacitance is initially charged to 1000 V. At t1=0, it is connected to a 1kΩ resistance. At what time t2 has 50 percent of the initial energy stored in the capacitance been dissipated in the resistance
A charge of 4 micro-Coulomb is applied to the surface of the car. If the car travels a distance of 2 meter between the two electrodes, and if the mass of the car is 200 grams, then what is the approximate time taken by the car to reach the second ..
Operation of NPN Bipolar Transistor : a. Describe the operation of a typical NPN bipolar junction transistor used both as an amplifier and a switch. b. List the 4 regions of operation and draw I-V characteristic curve.
A -6-nC point charge is located at the center of a conducting spherical shell. The shell has an inner radius of 2 m, an outer radius of 4 m, and a charge of +7 nC. (Let the radially outward direction be positive.)
