A parallel RC circuit is connected to a 100-volt 60 Hz source. The current flow through the resistor is measured and found to be 10amps. The current flow through the capacitor is measured and foundto be 10 amps.Determine(a) Line current (IT)(b) Impedance (Z)(c) True power (W)(d) Reactive power (VARs)(e) Apparent power (VA)(f) % PF (leading/ lagging)
Describe the performance differences between an AM and FM system. Be sure toinclude parameters suchas: Power efficiency, spectral efficiency,noise immunity,and performance.
a. Express the transfer function in descending powers of s with the coefficients of the highest power of s unity in both the numerator and denominator. b. Determine where the poles and zeroes of the transfer function are located.
An instructor in Engineering Department has the following grading policy: "Curving of grades is achieved by adding to every grade the difference between 99 and the highest grade in the class"
Assume that each donor atom contributes one free electron to the silicon lattice. For an n-type doping of 5x10^15 cm-3, how many silicon atoms are present for each lattice impurity
Write a C-program to generate K-map row and column headings for an arbitrary number of row or column input variables, i.e. 4x4 k-map for 2 row and 2 column variables, 16x16 k-map for 4 row and 4 column variables, etc.
An incandescent lightbulb rated at 60 W will dissipate 60 W as heat and light when connected across a 100-V ideal voltage source. A 100-W bulb will dissipate 100 W when connected across the same source.
A 20 vrms, 60 hz ac source is in series with an ideal diode and a 100 ohm resistance. Determine the peak current and peak inverse voltage (PIV) for the diode
b- Evaluate the sum of the second row of B. c- Multiply the second column of B and the first column of A. d- Evaluate the maximum value of the vector resulting from element-by-element multiplication of the second column of B with the first column ..
Design a DC power supply that provides -95v +/- 5v to a 2 amp load (energy absorber). The input source is a 100 volt peak sinusoid, 60 Hz. You may use any basic circuit element. State the values of all circuit elements (in ohms, farads, etc).
the output voltage of battery drop from 6V .With no load to 5.2V with a load current of 400mA. calculate the internal resistance.
Consider a diode biased at 1 mA. Find the change in current as a result of a changing the voltage by (a) -10 mV, (b) -5 mV, (c) +5mV, (d), +10mV. In each case, do the calculations (i) using the small-signal model and (ii) exponential model.
