Question

ammeter burns out when connected in parallel .give reasons?

Answer 1

An ammeter is likely to burn if connected in parallel because ammeter is a low resistance device and when connected in parallel, the resistance of the circuit reduces considerably. Hence, a large current flows in the circuit which may lead to burning of a circuit.

Answer 2

Reason why ammeter burns out when connected in parallel:

An ammeter is a device used to measure current and in order to measure the exact amount of current flowing in a circuit, it is made with low resistance properties.

Thereby, when the ammeter is attached in parallel connection, the current passing through the circuit in parallel connection becomes very large as compared to when connected in series as the current is equally distributed in each length of parallel circuit.

Due to the large amount of the current passing, and resistance less, the ammeter could not handle that ample of current and burns out.
