What is the term used for the positive electrode of a battery?

• A. Anode
• B. Cathode
• C. Electrode
• D. Terminal

Answer: (B)

The positive electrode of a battery is referred to as the cathode. In the context of electrochemical cells, during discharging, the cathode is the site of reduction, where positive ions gain electrons. This is where the chemical reaction takes place, allowing the battery to supply electrical energy to a circuit. Understanding the terminology is crucial; in a rechargeable battery, the roles of the electrodes can reverse during charging, but the definitions remain constant. Identifying the cathode as the positive electrode helps in grasping the functioning of batteries and electrochemical systems in general. This concept is essential for understanding how batteries operate in various applications, making it an important term within electrical engineering and electronics.
