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

can cost an organization their competitive edge. In the case of Circuit City According to Hitt‚ Ireland‚ & Hoskisson (2010) they implement a poor strategy and could not manage its inventory. No kidding I remember going to circuit city and they always have just about any movie in stock on the floor and many copies. As I have been taught in most of my business classes that inventory is one of the most expensive assets you can have. Circuit City let go of all the high paid employee in other words the

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

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

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
