Four resistors are connected in parallel. The values of the resistors are 1Ω, 3Ω, 4Ω, and 5Ω.
a. Using only a pencil and a piece of paper (no calculator), determine the current through each resistor if the current through the 5-Ω resistor is 6 A.
b. Again, without a calculator, solve for the total current applied to the parallel combination.
c. Use a calculator to determine the total parallel resistance of the four resistors. Use the current divider rule and the total current obtained in part (b) to calculate the current through each resistor.
A silicon wafer has a uniform doping density of 4x10^19 atoms cm^-3 of Arsenic and 4x10^19 atoms cm^-3 of Phosphorus. Assume that all atoms are fully ionized at room temperature.
An amplifier with 40 dB of small-signal open-circuit voltagegain, an input resistance of 1M-ohm ,and an output resistance10-ohm drives a load of 100-ohm .What voltage and power gains(expressed in dB) would you expect with the load connected
Design a Double Sideband Amplitude Modulation (DSBAM) modulator and demodulator system using the SystemView software. The modulating wave m(t) = Amcos(2pifmt) and the carrier wave c(t) = Accos(2?fct) have the following parameters
Construct a ladder schematic with a holding circuit to energize a relay. The relay when enerigized will turn one of and turn a different lamp on.
Determine the source voltage Vs of a 60-Hz power transmission system from the loading conditions described as follows: 1. The load is capacitive and absorbs 12 kW at 240
The number of cell phones recycled or refurbished instead of being sent to landfills is increasing by about 30% per year since 2004. In 2008, 5.5 million cell phones were recycled or refurbished. (a) Find an exponential model for the situation desc..
The main mission of this project is to design and build a tap changer which is going to be fitted to power transformers for regulation of the output voltage to required levels for the Micro Grid. The tap changer system will consist of 9 changers with..
Find the signal-interference ratio in dB when 120-sectoring antenna is used and the propagation coefficient n =3. If a cluster is replicated 10 times within the system, find the total number of users that can be served with this wireless cellular sy..
What is the Gain dB? I thought dB=20 log (Vout/Vin) This would lead me to believe that it should be 20 log (1.99/1) = 5.98 dB...I am being told the answer is -0.44 dB. What is my problem
A sequential circuit receives decimal numbers encoded in BCD one digit (4 bits) at a time, starting with the least significant digit. The circuit outputs are the 10's complement of the input number, also encoded in BCD least significant digit first.
A. For a particular MOSFET operating in the saturation region at a constant vGS, iD is found to be 1.4 mA for vDS = 0.1 V and 3 mA for vDS = 4.0 V. What is the value of VA (in V) B. For a particular MOSFET operating in the saturation region at a co..
How can you design a high gain (at least 20dB) operational amplifier with only pmos transistors In most designs, they include both nmos and pmos transistors. Is it possible to substitute the pmos for the nmos
