In this article we will discuss about the difference between Ammeter and voltmeter . we
will also know about the symbol of voltmeter and ammeter .
Difference between ammeter and voltmeter
Ammeter and voltmeter are used to measure current and voltage
respectively. A ammeter is an instrument
which is use to measure electric current in a circuit . A voltmeter is also a measuring device which
is use to measure potential difference between two point .
Working of voltmeter and Ammeter.
Ammeter is
use for measuring current and voltmeter is use for measuring voltage.
By using both
parameters we calculate the resistance of circuit by suing ohms law
V=IR
Where ..
V is Voltage ,
which is measure by Voltmeter
I is
Current , which is measure by Ammeter
R is Resistece which opposes flow of electric
current
For
measurement of current ammeter is to be connected in series to the circuit
Or if there
is AC current it can be measured by clam CT. but for measurement
Of current
only can be measured by two contact points.
Now let we know major differences between ammeter and voltmeter-
|
Ammeter
|
Voltmeter
|
|
1.Ammeter is use for measure amount of current
|
1. Voltmeter is use for measure potential difference between two
points.
|
|
2. Ammeter is connecting in series to measure current.
|
2. Voltmeter is connecting in parallel for measure voltage.
|
|
3. Ammeter has low resistance in its circuit.
|
3. Voltmeter has high resistance in its circuit.
|
|
4.it is less accurate as compared to voltmeter
|
4. It is more accurate as compared to ammeter.
|
|
5. For range extension of ammeters a low value resistance is connected
in parallel to the circuit, which is called shunt.
|
5. For range extension of voltmeter a high value non inductive
resistance is connected in series so that it measure high voltage as compared
to erlier.
|
|
6. Symbol of ammeter is
  |
6. symbol of voltmeter is
  |
Hence these
are some difference between Ammeter and
Voltmeter if you will find any incorrect
