Question

Why has an anmeter a
very low
resistance?​

Answer 1

Answer:

★Instruments are not supposed to disturb (change) the system they measure. In other words, the system with the instrument connected to it should behave the same way as without it.

★Instruments are not supposed to disturb (change) the system they measure. In other words, the system with the instrument connected to it should behave the same way as without it.★When you insert an ammeter into a circuit to measure the current flowing through a wire, you’re not supposed to change the resistance of that wire. Since the instrument is connected in series, any resistance within it gets added to the overall resistance of the wire it measures, so it has to keep its resistance as low as possible in order to leave the system unchanged
