what are the conditions satisfied by ammeter to measure current accurately?
Answers
What is Ammeter?
Ammerer is an electronic device connected in an circuit.
It is used to find out the amount of current flowing through the circuit ( I ).
CONDITIONS FOR CONNECTING AMMETER :-
=> AMMETER should be connected in series with the resistor to findout its current.
=> Ammeter is of low resistivity so small amount of current should be allow to flow through it if high current flows iy may broken down.
=> Ammeter shouldnot connect with voltmeter in series because voltmeter has high resistance which should be connected in parrallel.
VOLTMETER is a device used to find out potential difference across two ends of a conductor .
RELATION BETWEEN VOLT AND AMPERE :-
Ohm's law has put forward a relation between Voltage and current.
It states that Potential difference across two ends of a conductor is directly propertional to the current flowing through it.
This law also relates to a constant i.E resistance .

Answer:
Ammeter is an device which is used to measure the current in the wire in which current is flowing.
Explanation:
* Ammeter is made up of low resistance wire so that small amount of current is allowed to flow through the ammeter.
* If high current flows in the ammeter, the ammeter may be blasted or burnt due to large amount of current. Wire does not bear the heat of electric current.
* Ammeter is not connected in series combination because it is made up of low resistance wire so that it is connected in parallel combination.
