Question

Ammeter should have very low resistance

• A. for large deflection
• B. for better stability
• C. so that it may not burn out
• D. so that it may not change the value of the main current

Answer 1

The correct option is D so that it may not change the value of the main current

Ammeters are connected in series, so their resistance value is kept low enough because in series they measure the current passing through them so low resistance helps ammeter to detect the accurate value of current.

so we can say Ammeter should have low resistance so that it doesn't change the main current in the circuit
