Euler and Hamiltonian Circuits As I type this sentence millions of students all over the country are in their math class either a) struggling to open their eyelids or b) tapping their fingers due to boredom and impatience. They have all failed to understand how the topic would later come of use. Although mathematics may seem to be “unnecessary” it teaches our brains to strategize‚ and think differently through the use of trial and error and problem solving. Most individuals consider mathematics

Fire alarm circuit ABSTRACT Here is a simple fire alarm circuit based on a Light Dependent Resistor (LDR) and lamp pair for sensing the fire. The alarm works by sensing the smoke produced during fire. The circuit produces an audible alarm when the fire breaks out with smoke. When there is no smoke the light from the bulb will be directly falling on the LDR. The LDR resistance will be low and so the voltage across it (below 0.6V). The transistor will be OFF and nothing happens. When there is sufficient

Differentiator and Integrator Circuits Submittal Date: 6/11/2014 Objectives: 1. To demonstrate the operation of a differentiator 2. To demonstrate the operation of an integrator Results: The differentiator circuit caused the cosine wave to output a sine wave and a triangle wave to output a square wave. The Integrator circuit caused the sine wave to become a cosine wave and the square wave into a triangle wave. Conclusions: The differentiator circuit differentiates the wave

Compare and contrast circuit-switched services‚ dedicated-circuit services‚ and packet-switched services. Circuit switches services uses cloud architecture. This happens when a user leases a connection from a known carrier (which is called a cloud). This works for telephone lines; the user dials the telephone number of the destination computer and establishes a temporary circuit between the two computers. The computer then exchanges various data till the task is finished. When the task is completed

CIRCUITS LABORATORY EXPERIMENT 3 AC Circuit Analysis 3.1 Introduction The steady-state behavior of circuits energized by sinusoidal sources is an important area of study for several reasons. First‚ the generation‚ transmission‚ distribution‚ and consumption of electric energy occur under essentially sinusoidal steady-state conditions. Second‚ an understanding of sinusoidal behavior makes possible the prediction of circuit behavior when nonsinusoidal sources are used through the use of techniques

Questions and Problems: 1. Describe the type of meter movement used in analog meters. The current in the circuit is used in basic meters to measure the voltage drop or current in the circuit. The current passes through the coils of wires‚ which is then magnetized. Inside the apparatus‚ there is also a permanent magnet which opposes the magnetic field of the magnetized coil of wire that is connected to the pointer therefore‚ as we see in meters‚ the pointer moves. There is also a spring connected

"The History of the Integrated Circuit" In today’s world integrated circuits are everywhere we turn. Many of them you will find in computers. For example the microprocessor is an integrated circuit that processes all information in the computer. It keeps track of what keys are pressed and if the mouse has been moved. It counts numbers and runs programs‚ games and the operating system. Chip production today is based on photolithography. In photolithography a high energy is shone through a mask
