one ammeter is a device used to measure the amount of existing flowing in a circuit.
You are watching: Why do ammeters have low resistance
The resistance of an ideal ammeter have to be zero.
This is since an ammeter is linked in series in a circuit.
Hence, it"s resistance adds come the complete resistance the the circuit.
If the resistance of the ammeter would certainly be high, the full resistance would certainly be high.
This would certainly decrease the quantity of present flowing v the circuit.
Hence, in bespeak to protect against the readjust of current flowing in a circuit.
The resistance of one ammeter must be as small as zero.
