RC Circuits question

Question

You're given 2.30 g of aluminum and asked to make a wire, using all the aluminum, with a resistance of 2.00 Omega.

What (a) length and (b) diameter will you choose for your wire?

I have no idea about even how to approach this problem. Any help would be greatly appreciated!

Answer 1

1st answer is correct, that the answer alone won't help you in the long run. But some advice on solving the problem should:

Find out density d and specific volume resistivity ρ of aluminum.

Calculate volume V from mass and d.

Resistance = ρ*length/area

Since volume V = length*area, resistance = ρ*V/area^2

Then do the math to solve for area, diameter and length.

Answer 2

(a) This question has nothing whatsoever to do with capacitors; why is your title "RC Circuits" (resistor/capacitor circuits)?

(b) Read about calculating conductivity and resistivity. Apply what you learn.

(c) Somebody giving you the answer here will not help your understanding, which is clearly deficient, one bit.
