a) The switch in a RC circuit is closed. If the resistance is 134462ohms, the capacitance 7.5 microF, and the applied voltage 18 volts, what is the (average) rate of change of the voltage on the capacitor, to the nearest tenth of a V/s, during the first time constant period?
b) If the capacitor in the previous problem has a plate separation of 1 mm, what is the average displacement current, to the nearest tenth of a microamp, during that time period? Assume a resistance of 180006 ohms and an applied voltage of 14 volts.
Consider a multimode silica fiber that has a core refractive index of n1 = 1.48 and cladding index n2 = 1.46. Find the critical angle, numerical aperture and the acceptance angle.
A room has four doors and four light switches (one by each door). Sketch a circuit that allows the four switches to control the light - each switch should be able to turn the light on if it is currently off, and off if it is currently on.
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..
You must design a three axis position indicator for the latest robot arm. Using no more than two operational amplifiers, design a circuit that uses three inputs, v1, v2, and v3 to produce an output signal vo=3 v1-2 v2-5 v3.
A series type Ohmmeter uses a 50 ohm, 1mA PMMC the internal battery voltage is 3V the desired scale marking for half scale deflection is 2000 ohm. Calculate:- - Value of R1 & R2
Describe whether Google is exploitive, impoverished, supportive, or enlightened. Describe the features google that indicate which kind of organization it is. Describe five steps google could take to become better and move up in the scale.
A coaxial line 5.6m long has distributed parameters R=6.5ohm/m, L=3.4 uH/m, G=8.4 mS/m, and C=21.5 pF/m. If the line operates at 2MHz, calculate the characteristic impedance and the end-to-end propagation time delay.
Important information about Noise, Explain the role of the central limit theorem in the behavior of Additive White Gaussian Noise (AWGN).
Identify the type of cable that is permitted in single- and multifamily dwelling units but that cannot be used underground, nor in buildings that are more than three stories above grade, nor in commercial garages, motion picture studios, theaters,..
The system contains a door sensor, a window sensor, and a key activation switch. If the switch is on, opening the window will set off the alarm immediately. Opening the door will start a 30 second timer.
Assessment on Electricity and Circuit Theory, What part of a cable are insulators and conductors? Describe, in terms of charged particles, why some objects are electrically attracted to each other, while others repel each other?
In a binary digital communications systems, the bit energy required at the receiver input terminals is 50x10^-18 JOther parameters are as follows: Gt(dB)=24 dB Gr(dB)= 26 dB f= 10GHZ d=40,000 km
