The current in the wire is given by:

$\overline{){\mathbf{I}}{\mathbf{=}}\frac{\mathbf{\u2206}\mathbf{V}}{\mathbf{R}}}$

A wire with resistance R is connected to the terminals of a 6.0 V battery. What is the potential difference ΔV between the ends of the wire and the current I through it if the wire has the following resistances?

a. 1.0 Ω

b. 2.0 Ω

c. 3.0 Ω
