Laboratory Long report. Electronic laboratory practice Abstract: The aim of this laboratory was to make us familiar with how to use the different types of electronic equipment and how to accurately use them to make measurements. The equipment used in this laboratory included: (i) the signal generator which was used to supply the power used in the various procedures‚ (ii) The oscilloscope which was used to view and record the waves produced from the AC currents and then make relevant calculations

If the ratio of the two resistances in the known leg is equal to the ratio of the two in the unknown leg ‚ then the voltage between the two midpoints (B and D) will be zero and no current will flow through the galvanometer . If the bridge is unbalanced‚ the direction of the current indicates whether is too high or too low. is varied until there is no current through

FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF BACHELOR OF SCIENCE IN ELECTRICAL ENGINEERING OCTOBER 2010 I. INTRODUCTION An analog multimeter is a device that is composed of various meters combined. Such instrument can measure resistance‚ voltage and current. It is commonly known as volt-ohm meter or VOM. This device can also determine the continuity in a circuit and it measures with high accuracy. In this project‚ a VOM was built using the given parameters and tested it in various circuits

Comparison of voltages in each substation with the results got from Bewley Lattice Diagram and simulation results are shown in below‚ Substation A Substation B Substation C Substation D When we compare simulation results with the graphs we got using Bewley lattice diagram there are some differences we can see. Although when we draw our graphs using Bewley lattice diagram‚ we tend to draw step wise voltage increment or

Abstract: The main aim of this assignment is to design a pre amplifier circuit with an NPN transistor to be used in a simple public address (PA) system. The pre amplifier is fed from a microphone that produces an average output voltage of 10 mV rms. The amplifier is to operate over a frequency range of 300 Hz to 5 kHz and should have an adjustable volume control. The expected gain of the amplifier is 100. First we are going to design an amplifier for given specifications‚ model the operation of the

HARSH KUMAR A voltmeter is an instrument used for measuring the electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display of voltage by use of an analog to digital converter. Voltmeters are made in a wide range of styles. Instruments permanently mounted in a panel are used to monitor generators or other fixed apparatus. Portable instruments‚

though it may also refer to devices that convert another form of energy (mechanical‚ chemical‚ solar) to electrical energy. A regulated power supply is one that controls the output voltage or current to a specific value; the controlled value is held nearly constant despite variations in either load current or the voltage supplied by the power supply’s energy source. Power supplies for electronic devices can be broadly divided into line-frequency (or "conventional") and switching power supplies. The
