Electrolysis Practice Exam

Question: 1 / 400

What is an ohm a unit of?

Power

Resistance

An ohm is indeed a unit of resistance. It quantifies how much a material opposes the flow of electric current. When a voltage of one volt is applied across a conductor and results in a current of one ampere flowing through it, the resistance of that conductor is one ohm. This relationship is described by Ohm's Law, which states that voltage (V) equals current (I) multiplied by resistance (R).

Understanding resistance is fundamental in electrolysis because it influences the efficiency and effectiveness of the process. For example, higher resistance in the electrolytic cell can lead to lower current flow, affecting the overall yield of the electrolysis reaction.
