Today’s Experiment Exp. No. : 01 Name of the Experiment: Familiarization with some electric equipment’s and measurement of voltage, current, power for both AC and DC supply.
AC Alternating current describes the flow of charge that changes direction periodically.
DC Direct current (DC) is the unidirectional flow of electric charge. Direct current is produced by sources such as batteries, power supplies, thermocouples, solar cells, or dynamos
Task!!!!!! How can you measure these AC or DC voltage or Current? ? ?
Commonly used Electric Meters Ammeter Voltmeter Wattmeter AVO meter, Commercially called Multimeter
Ammeter An ammeter is a measuring instrument used to measure the electrical current in a circuit. Electric currents are measured in amperes (A). Types: 1. DC Ammeter 2. AC Ammeter
Schematic Diagram of Ammeter: Ammeter Should always be connected in Series with Load
Pictorial View of DC & AC Ammeter DC Ammeter AC Ammeter
Voltmeter v. Used to measure Electrical potential difference between two points in an electric circuit. Voltage are measured are Volt (V). Types: 1. DC Voltmeter 2. AC Voltmeter
Schematic Diagram of Voltmeter: Voltmeter must be connected in Parallel with Load
Connection Diagram of Voltmeter:

Multimeter/AVO meter: A typical multimeter would include basic features such as the ability to measure voltage, current and resistance
Wattmeter Measures the Electric power in watts Types: 1. Analog Wattmeter 2. Digital Wattmeter
