Question

1) How is ammeter connected in a circuit to measure current flowing

through it? What happen to resistance of a conductor where its area of

cross- section is increased?​

Answer 1

Answer:

Ammeter is connected in series to the circuit.

When area of cross-section is inctreased its resistance decreases.....

Answer 2

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.
