If you have two wires A & B made of same material with A being twice as thick as B, when using the formula I = n A q V will the value of n and Q remain the same for both wires or will they change?
I think because the A wire is more thick it therefore has more valence electrons that can carry charge and therefore the number of charge carriers should increase compared to wire B. But i think i heard someone say that n & q remains constant and only A & V value changes.
