Question

Assertion: In a circuit the ammeter reading is decreased

when a thicker wire of the same material and of the same

length is used.

Reason: The resistance of the conductor depends on its length

and area of cross section and on the nature of the material.​

Answer 1

Answer:

Notice the difference in the current in all cases. When the length of the wire is doubled, then the ammeter reading decreases to half its previous value i.e., current through the wire is halved. Since, resistance of the wire , then R is doubled which implies R x L.
