What term describes the opposition to the flow of electric current?

The term that describes the opposition to the flow of electric current is resistance. In an electrical circuit, resistance is a fundamental property that measures how much a material or component resists the flow of electricity. It plays a crucial role in determining how much current will flow for a given voltage, as described by Ohm's Law (V = IR), where voltage (V) is equal to the current (I) times resistance (R).

This concept is vital in electrolysis, as resistance can affect the efficiency and efficacy of the process. A higher resistance in the electrolysis cell can lead to lower current flow, which may impact the overall outcomes of the electrolysis treatment.

To clarify the other terms: voltage refers to the potential difference in electric charge, current is the flow of electric charge, and power is the rate at which electrical energy is transferred. While all these terms are related to electricity, resistance specifically denotes the opposition to current flow, making it the correct term in this context.
