Hi there, I'm a student in high school.(adsbygoogle = window.adsbygoogle || []).push({});

I'm quite new to the forum. Please forgive my mistakes.

The problem statement, all variables and given/known data

My question is related to electricity, more specifically the factors affecting resistance in a wire. I know that resistance is inversely proportional to the cross-sectional area of the wire.

Does the number of wires represent the cross-sectional area of the wire?

Relevant equations

The circuit diagram is in the attachment.

I came across an experiment which describes that by changing the number of wires (ie. changing the number of eureka wires), we actually change its cross-sectional area.

The attempt at a solution

However, doesn't adding the number of wires make it become a parallel circuit?￼

Help to clarify please?
