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

Integrated Curriculum Defining integrated curriculum has been a topic of discussion since the turn of the 20th century. Over the last hundred years‚ theorists offered three basic categories for interdisciplinary work; they defined the categories similarly‚ although the categories often had different names. Integration seemed to be a matter of degree and method. Integration: The unification of all subjects and experiences. There I have defined three approaches to integration a) Multidisciplinary

An Investigation on Capacitance and RC circuit Hamdy Hamdy Abdel Moneim Abdou‚ Jaime Lorenzo C. Olivares‚ and Karol Giuseppe A. Jubilo National Institute of Physics‚ University of the Philippines‚ Diliman‚ Quezon City Abstract This experiment is designed to further the understanding of the relationship between voltage‚ charge‚ and capacitance of capacitors. This also explains how values of effective capacitance for series and parallel combinations of capacitors are

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

| Resistance and Electric Circuits | Lab 5 | | | The goal of the “Resistance and Electric Circuit” Lab was to determine the resistivity of a conducting wire given two known resistors. The main property of resistivity is that it represents how easily electrons can flow through a material. A Galvanometer is used to measure the current of the circuit and the Wheatstone Bridge is used to measure the resistances and determine the unknown resistance. This experiment also relates Ohm’s Law

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

Advantages of Digital Circuits Name: Instructor: Institution: Introduction Digital circuits are circuits that use signals in digital form instead of analog forms. One distinctive feature of a digital signal is that it assumes discrete values‚ most of the time two values. A digital signal takes time to change from one value to another‚ and assumes intermediate values during transmission (Verma). Steady values are slightly inaccurate. Voltages
