*Question T6B09:
What are the names for the electrodes of a diode?*  

*Correct Answer is  C: Anode and cathode*  

### AI Response: (may contain errors)  

The correct answer to the question about the electrodes of a diode is **C: Anode and cathode**. 

### Explanation of the Correct Answer:
- **Anode and Cathode**: 
  - In a diode, the **anode** is the positive side where current enters, and the **cathode** is the negative side where current exits. 
  - When a diode is forward-biased (i.e., the anode is more positive than the cathode), it allows current to flow through it.

### Why the Other Choices are Incorrect:
- **A: Plus and minus**: 
  - While these terms describe the polarity of the anode and cathode, they are not the specific names used in the context of diodes.
  
- **B: Source and drain**: 
  - These terms are used in the context of field-effect transistors (FETs) and not applicable to diodes. The source is where current enters, and the drain is where it exits in a FET.

- **D: Gate and base**: 
  - The **gate** is a control terminal in FETs, and the **base** is a terminal in bipolar junction transistors (BJTs). Neither term applies to diodes.

### Summary:
- The terms **anode** and **cathode** are specific to diodes and are essential for understanding how they function in circuits. Remembering these terms will help you in both the exam and practical applications in electronics.
