Ammeter is likely to burn out if you connect it in parallel because:a)...
An ammeter is likely to burn if connected in parallel because :
1)an ammeter is a low resistance device
2)when connected in parallel , resistance of the circuit reduces considerably hence , a large current flows through the circuit which may lead to burning of ammeter
hope u got it

Ammeter Basics
An ammeter is an instrument used to measure the electric current flowing through a circuit. It is designed to have low resistance to ensure that it does not significantly affect the circuit being measured.
Why Connect in Series?
- Ammeters should be connected in series with the circuit.
- This configuration allows the ammeter to directly measure the current without altering the circuit's operation.
Risk of Connecting in Parallel
When an ammeter is connected in parallel, several issues arise:
- Low Resistance: Ammeters are constructed with very low resistance to minimize the voltage drop across them. This design is crucial for accurate current measurements.
- Excessive Current Flow: If connected in parallel, the ammeter effectively acts as a short circuit. Since it has low resistance, it allows a large amount of current to flow through it, which is far beyond its designed capacity.
- Burnout Risk: The excessive current can lead to overheating, causing the ammeter to burn out or get damaged.
Conclusion
In summary, connecting an ammeter in parallel poses a significant risk because:
- It has low resistance.
- This low resistance allows excessive current, which can lead to failure.
Always ensure that ammeters are connected in series to prevent damage and obtain accurate measurements.
