Question

Which one has the lowest resistance - ammeter, voltmeter or galvanometer? Explain.

Answer 1

Answer:

An ammeter has the lowest resistance because to measure the current in a circuit whole current should flow through the ammeter . And this can only happen if ammeter has least resistance .

So , ammeter has lowest resistance then galvanometer then voltmeter .

Thanks ♥️

Answer 2

• The resistance of the ammeter is the lowest. In the series connection, the ammeter is connected in a circuit.
• A galvanometer can be turned into an ammeter by connecting it to a low resistance shunt in parallel with it.
• When resistors are connected in parallel, the network's effective resistance is smaller than the individual resistance.
