Laboratory Report Title of Experiment: Series and Parallel Circuits Date Given: January 28‚ 2013 AIM: To investigate the circuits to tell whether the resistors are in parallel or in series also to determine the internal resistance of a 1.5V cell. THEORY: In this experiment it was expected of the experimenter to have a basic knowledge of circuits in both aspects theoretically and practically. A basic circuit comprises of a cell or power supply (some electric driving force) a

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

Sears‚ Roebuck and Co. Vs. Wal-Mart Stores‚ Inc Problem: Don Edwards‚ a recent MBA graduate has been asked to analyze the financial performance of Sears and Wal-Mart. Although Wal-Mart is the industry powerhouse‚ its 20% return on equity (ROE) lags behind that of Sears’ 22%. Analysis: Wal-Mart operates fewer stores than Sears but is ahead in terms of total selling area by a ratio of 3.4:1. Between 1995 and 1997‚ Sears’ retail store revenue per selling square foot was not only lower

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

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
