Why is ammeter likely to burn when connected in parallel in the circuit?
Current means flow of charge (free electrons) in define direction.
I =Q/t
Current is measured by Ammeter.
Ammeter has very low resistance.
Ammeter is connected in series ..more amount of current flow through it due to low resistance..it act like closed switch..so it indicates the current.
Now, Ammeter is connected in parallel..due to low resistance act like short circuit..chances of ammeter get damaged.
So, Ammeter is always connected on series.
