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

the Norton’s theorem. EQUIPMENT Resistor 100Ω‚ 1kΩ and 4.7kΩ‚ digital multimeter(DVM)‚ bread board. INTRODUCTION Some circuits require more than one voltage source. Superposition theorem is a way to determine currents and voltages in a linear circuit that has multiple sources by taking one source at a time. the current in any given branch of a multiple-source linear circuit can be found by determining the currents in that particular branch produced by each source acting alone‚ with all other sources

| 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

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
