n an experiment, James used the thinnest wire he could find to connect a battery to a light bulb. He found that the bulb light up dimly. He then changed to thicker wires and repeated his experiment, noticing that the light bulb kept getting brighter. Assuming every wire was made from the same conductor (copper) which of the following explanations is most reasonable?(1 point)

Responses

James must have had a bad connection because the light bulb should have illuminated to the same brightness.

A metallic conductor becomes an insulator as it decreases in thickness.

Small items are good insulators, while large items are good conductors.

Thin wires do not allow as much electricity to flow as thicker wires.

The most reasonable explanation for James's observations is:

Thin wires do not allow as much electricity to flow as thicker wires.

Thicker wires have a lower resistance compared to thinner wires, which allows more current to flow through the circuit. This increased current is what causes the light bulb to illuminate more brightly.
