Question 1

How much current will flow through a length of metal wire with a radius of if it is connected to a power source supplying The resistivity of the metal is 1.68 × 10-8 Ω ∙ m.
◦ 0 A
◦ 0 × 108 A
◦ 0 nA
◦ 0 A

Question 2

When a potential difference is applied across a piece of wire made of metal A, a current flows.  If the metal-A wire is replaced with a wire made of metal B having twice the diameter of the metal-A wire, how much current will flow through the metal-B wire? The lengths of both wires are the same, and the voltage difference remains unchanged. The resistivity of metal A is 1.68 × 10-8 Ω ∙ m, and the resistivity of metal B is 1.59 × 10-8 Ω ∙ m.
◦ 21 mA
◦ 19 mA
◦ 5.3 mA
◦ 11 mA
