Question

Will current flow more easily through a thick wire or a thin wire of the same material, when connected to the same source? Why?​

Answer 1

Answer:

Explanation:

The current will flow more easily through the thick wire than the thin wire. It is because the resistance of a conductor is inversely proportional to its area of cross-section. If the thicker the wire, the less is resistance and hence more easily the current flows.

Answer 2

Answer:

As per ohm’s law of electrical resistance, the thickness of the conductive wire is inversely proportional to the amount of resistance. The quantity of electrons in the thin wire is lower due to the less conductive surface.

• A thick wire has a greater diameter and hence lesser resistance making the current flow more easily.
• On the other hand, a thin wire has a smaller diameter and greater resistance to the current through it.
• The current will flow more easily through the thick wire than the thin wire.
• It is because the resistance of a conductor is inversely proportional to its area of cross-section.
• If the thicker the wire, the less is resistance and hence more easily the current flows.

Note:

• The resistance in a wire increases as:

• the length of the wire increases, the thickness of the wire decreases
