What does Faraday's Law state regarding deposition in a circuit?

• A. The weight of material deposited on the cathode is proportional to the charge
• B. The total opposition that a circuit presents to AC
• C. A voltage differential between two components of a system
• D. An increase in current results in a decrease in resistance

Answer: (A)

Faraday's Law of Electrolysis states that the mass of a substance deposited or dissolved during electrolysis is directly proportional to the quantity of electricity that passes through the circuit. This principle is crucial in understanding electrochemical processes, particularly in applications such as plating and corrosion prevention. When focusing on deposition in a circuit, the law emphasizes that the weight of the material deposited on the cathode (the electrode where reduction occurs) is proportional to the total electric charge that flows through the circuit. This means that if more charge passes, more material will be deposited, illustrating a direct relationship between charge and deposition weight. This principle is foundational in electrochemistry and is essential for those involved in corrosion prevention and control, as it helps predict and measure how much protective coating or substance can be deposited in a given time based on the current supplied. Understanding this relationship is key in designing and troubleshooting electrochemical systems.
