Answer:
Ammeter is connected in series to the circuit.
When area of cross-section is inctreased its resistance decreases.....

Answer:
♢ An ammeter is connected 'in series'.This means that it is connected such that all the current must flow through it.
♢ The resistance of a conductor is inversely propotional to its area of cross section.As the amount of current flowing at voltage increases with increase in cross section area, resistance decreases.
