A silicon photovoltaic cell is employed in the circuit shown in Figure. The cell has an internal resistance of 65Ω. A light pulse of 20-ms duration and intensity strikes the detector.
Sketch the output voltage versus time, and find the maximum voltage produced. The cell calibration voltage is V0 = 0.60 V.
A two-resistor voltage divider consists of a 10 k and a 15 k ohm resistor, with the 10 k resistor connected to the voltage source and the 15 k resistor connected to ground. If the output voltage is 2.5 V across the 10 k resistor
If the local government can enforce a rent-control law that sets the maximum monthly rent at 1500, will there be a surplus or a shortage? Of how many units? And how many units will actually be ranted each month?
What is the constraint span of the convolutional coder shown in Figure 11.47? How many states are required to define the state diagram and the trellis diagram? Draw the state diagram, giving the output for each state transition.
The nameplate on a 50 kVA transformer shows a primary voltage of 480 V and a secondary voltage of 120 V. We wish to determine the approximate number of turns on the primary and secondary windings.
Derive the two-term including source match error correction formula. Note: For all of these derivations, you should identify your standards {match, short, open} but DO NOT assume anything about their values.
Design a digital circuit that can be attached to a school bill which can work automatically from 7:00 AM to 12:45 PM, and it has the following features: 1- Rings for 5 seconds. 2- Start ringing 7:00 AM to announce for the field gathering. 3- Rings 7:..
the bottom of the conduction band at one end of a silicon resistor is at the same energy level as the top of the valence band at the other end. What current flows through the resistor if the resistance is 1.12k
A single phase transformer rated 1.2kV/120V, 7.2kVA hasprimary-referred parameters Req= r1+ a r2= 1Ω andXeq = x1+ a2 x2 =4Ω when neglecting exciting current. At rated voltage itscore loss may be assumed to be 40W for all the load curent.
A force Farrowbold applied to an object of mass m1 produces an acceleration of 3.40 m/s2. The same force applied to a second object of mass m2 produces an acceleration of1.60 m/s2. If m1 and m2 are combined into one object
Design an interface for a ±24 V, 500 mA geared DC motor. The time constant of the motor is 10 ms. Include software to adjust the delivered power from 0 to 100%.
Usually, transformers are designed to operate with peak flux densities just below saturation of the core material. Why would we not want to design them to operate far below the saturation point? Far above the saturation point? Assume that the vol..
Write a program in C not C++ that reads 20 integers from the user and sums the odd and even numbers together. Also have the program output the ratio of the odd numbers to the even numbers.
