If a wire has high resistance, what can be inferred about its ability to conduct current?

Explanation:
High resistance means the material resists the flow of electric charge. Using Ohm’s law, current equals voltage divided by resistance. If resistance is large, the same voltage pushes only a small amount of current, so the wire conducts poorly. The wire is not a good path for current, even if you increase the voltage somewhat.
