The current price of gold costs $58,887.31 per kilogram while silver costs $864.19 per kilogram. The density of gold is 19.32 [g]/[cm]^3 while silver is 10.49 [g]/[cm]^3. A)If you desired to create electrical wires that are both 10 [m] long, how thick or thin would the gold wire be compared to the silver wire if you desired for them to have the same electrical resistance? (i.e. - find the difference in diameters.) B)Given the situation in part a, how much more would the gold wire cost in comparison to the silver wire?

Microscopic view of current

In physics, the term current is expressed as the rate of flow of electric charges across the area per unit time (I=q/t). It propagates along in the direction of the motion of positive charges. When the current is caused by the motion of electrons, the direction of the current is opposite to the flow.
