For an ammeter, voltmeter and galvanometer having resistances $R_{A}, R_{V}$ and $R_{G}$ respectively, the correct relation among these resistances.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → $R_{A}<R_{G}<R_{V}$
Ammeter has law resistance $(R_A)$ to minimize its effect on current.
Voltmeter has high resistance $(R_V)$ to minimize the current it drawn when measuring voltage.
Galvanometer has an intermediate resistance $(R_G)$ because it needs to detect small currents.
$∴R_{A}<R_{G}<R_{V}$
