In moving iron type ammeter the coils has few turns of thick wire.
In a moving coil type ammeter, the coil has a few turns of thick wire.
This is because the coil of a moving coil type ammeter is connected in series with the circuit being measured, and the voltage drop across the coil is proportional to the current flowing through the circuit.
Therefore, the coil should have a low resistance to minimize the voltage drop across it and to obtain an accurate reading of the current flowing through the circuit.
If a moving iron type ammeter, the coils are made up of a large number of turns of fine wire, which offers a higher resistance to the current flowing through it.
This is because the ammeter is designed to measure the current flowing through a circuit and it should not affect the circuit operation by drawing a significant amount of current from it.
Therefore, the resistance of the ammeter should be as low as possible.
