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

are control circuits to represent. If we wanted to draw a simple ladder diagram showing a lamp that is controlled by a hand switch‚ it would look like this: The "L1" and "L2" designations refer to the two poles of a 120 VAC supply‚ unless otherwise noted. L1 is the "hot" conductor‚ and L2 is the grounded ("neutral") conductor. These designations have nothing to do with inductors‚ just to make things confusing. The actual transformer or generator supplying power to this circuit is omitted

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
