8. 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
Voltage Source: A voltage source is a
two terminal device which can maintain
a fixed voltage.

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

12. Ammeter
•A current measuring instrument
•Measures the amount of current flow through
the circuit
•Ammeter is a low resistance device

13. Ammeter is always connected in series with
the branch whose current is to be measured

14. Voltmeter
•To measure electrical potential difference
between two points in an electric circuit
•Voltmeter is a high resistance device

15. Voltmeter must be always connected across the load

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

17. 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.)
