Question

what is ammeter reading

Answer 1

Answer:

Explanation: Ammeter

• It is a instrument which helps in measuring ammeter the current in a circuit.
• Since it is measured in amperes it is referred as ammeter.
• To measure smaller currents the instrument one uses is microammeters or milliammeters. These are used to measure current which are in milliampere or microampere range.
• During early stages ammeters would operate depending on the Earth's magnetic field.
• Gradually improved instruments came into existence which could be placed in any position which helped in getting exact measurements in electric power systems.
• Ammeters are designated in a circuit by the letter 'A '.
• By Ammeter reading we mean reading of the deflection of the magnetic needle which takes place because of the intensity of the magnetic field which takes place in the ammeter coil because of the amount of current flowing.
• Once calibrated the instrument is capable of measuring the quantum of current flowing once connected in series in the circuit.

Hope this helps.
