Spidey

Spidey, think of it this way. Why would you need to insulate something? then the logical continuiation of that would be, why would you need to insulate copper? You figure that out, then you have figured out that whatever shortcoming copped has that requires insulation, that aluminum just doesn't have.

Can you repeat it once again clearly. I am confused.

Hi,

I am Spidey. I am new.

Hello,

Though the questions that I post in this Homework help section are actually not related to my homework but appear in my 9th STD physics text book with the label "Think It Over", I feel it is appropriate to post them here, because even after much thinking I have not been able to find right explanation.

The question is- "The aluminium wires used in the transmission of electric current are not insulated. Why?"

Thanks.

Hello,

I got into the same question when I was studying in 9th STD and I am still looking for the answer. Please tell me the answer if you get it.
