The opposition that a device or material offers to the flow of a direct current

Explanation:
Opposition to the flow of direct current is called resistance. This quantity determines how much current will pass for a given voltage, following Ohm's law (V = IR). In AC contexts, impedance is the broader term that includes reactance, but for direct current the opposition is simply resistance. The unit of resistance is the ohm, not the term itself, and conductivity is the material’s ability to conduct electricity (inversely related to resistance).
