7. Exp. No: 01 Exp. Name: Familiarization with some electric meters and circuit equipment.
Circuit: A close conducting path through which an electric current either flows or intended to flow
Electrical Parameters: The various elements of an electric circuit are called its parameter, like resistor, inductor, capacitor, voltage source, current source etc.
Active Elements: Voltage source, Current source
Passive Elements: Resistors, Inductors, Capacitors

8. Active Elements
Voltage Source: A voltage source is a two terminal device which can maintain a fixed voltage.
Current Source: A current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it. i.e. which can deliver a constant current.

13. Electric Meter Different Electrical Meters for Measurement Purpose:
Galvanometers
Ammeters
Voltmeters
AVO meter (Commercially called Multimeter)
Wattmeter

14. Ammeter
A current measuring instrument
Measures the amount of current flow through the circuit
Ammeter is a low resistance device
Ammeter is always connected in series with the branch whose current is to be measured

15. Connection Diagram of Ammeter

16. Ammeter Two types _ DC Ammeter _ AC Ammeter
A DC ammeter is polarity marked with +Ve and –Ve sign
The +Ve polarity of DC ammeter have to be connected to the current entering side of the circuit

17. This mark of straight line indicate DC ammeter
Range Extension

18. This mark of straight line indicate AC ammeter
Range Extension

19. Voltmeter have to be always connected across the load
To measure electrical potential difference between two points in an electric circuit
Voltmeter is a high resistance device
Voltmeter have to be always connected across the load

20. Connection Diagram of voltmeter

21. Voltmeter Two types _ DC Voltmeter _ AC Voltmeter
In a DC voltmeter the terminals are provided with polarity marking (+Ve and –Ve)
To use DC voltmeter precaution should be taken about the polarity marking
In an AC voltmeter there is no such polarity marking

22. This mark of straight line indicate DC voltmeter
Range Extension

23. This mark of straight line indicate AC voltmeter

24. Multimeter It is also known as Electronic VOM or AVO meter
Used to measure current, voltage and resistance both for AC and DC quantity, for a number of ranges
Some multimeter provide the facilities of measuring inductance, capacitance, temperature
Two type _ Analog AVO meter
_ Digital AVO meter

25. Multimeter
Analog Multimeter
Digital Multimeter

26. Wattmeter To measure electric power in a circuit
Wattmeter is generally four terminal device
Two terminal are the end points of potential coil (P.C.) and the other two are current coil (C.C.)

27. Wattmeter
Basic Wattmeter connection

28. Wattmeter
Analog Wattmeter
