    INTRODUCTION A voltmeter finds its importance wherever voltage is to be measured. 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. General purpose analog voltmeters may have an accuracy of a few per cent of full scale‚ and are used with voltages from a fraction of a volt to several thousand volts. Digital voltmeters give a numerical

    converter. It is a 10-bit ADC which uses the in-built reference voltage level of 2.5V. Software Implementation: The programming required‚ reading the input signal from the ADC pin and then to display the voltage on the alphanumeric LCD‚ is done using Bascom-AVR. Though the features of an actual oscilloscope have been compromised upon but the essence of its hardware has been conserved by implementing a voltage reading device. CHAPTER-1 INTRODUCTION The oscilloscope is one of the

    How voltmeter and ammeter work Measuring Voltage Measuring the voltage between two points of an electrical current can be done with an instrument called a voltmeter. One type of voltmeter is a direct-current voltmeter. When taking a voltage reading the instrument is placed across the portion of the circuit that is to be measured. Direct-Current Voltmeter The direct-current voltmeter has a horseshoe shaped magnet‚ with a semicircular piece of soft iron attached to each end of the magnet. The iron
