DANB Radiation Health and Safety (RHS) Practice Exam

In an electric circuit, which terminal is the positive electrode?

1. Cathode

2. Anode

3. Yoke

4. Timing device

The correct answer is: Anode

In an electric circuit, the positive electrode is referred to as the anode. The anode is the terminal that attracts negatively charged particles or ions, making it the positive side of a circuit in electrochemical processes. In various applications, including batteries and electrolytic cells, the flow of electrons occurs from the anode to the cathode, which is the negative electrode. Understanding the role of the anode is critical in both practical applications and theoretical concepts. This knowledge is essential for those working with electronic devices, as it helps in comprehending how electric currents flow and how circuits function. The other terms provided, such as the cathode, yoke, and timing device, refer to different components or concepts that do not represent the positive terminal in an electric circuit. The cathode, for example, is always the negative electrode in the context of an electrochemical setup.
