Question

An ammeter, ideally, has:

Options

• very high net resistance (ideal voltmeter → ∞ Ω) and is connected in parallel

• infinite resistance and is connected in series

• zero resistance and is connected in parallel

• very low net resistance (ideal ammeter → 0 Ω) and is connected in series in the circuit

Answer 1

Since the shunt S is very small, most of the current bypasses the galvanometer and the ammeter has a very low net resistance (ideal → 0 Ω). It is connected in series so the entire circuit current passes through it.
