5.
**I. Fill in the blanks:**
1. Atoms are the smallest units of matter.
2. The flow of electrons from the negative terminal of a source to the positive terminal in a closed circuit is called **current**.
**II. True or false:**
1. False - Gold and steel are examples of conductors.
2. True - Electrodes are commonly made of metals such as platinum and zinc.
3. False - Electroplating is the process by which a metal is coated with a thin layer of another metal by electrolysis.
4. False - Electrical conductivity involves the flow of current of free electrons through a solid body.
5. False - Pure water is a poor conductor of electricity.
**III. Answer the following:**
1. **Define electroplating. Write one use of electroplating.**
- **Electroplating:** The process of depositing a layer of a desired metal on another material by means of electricity.
- **Use:** Electroplating is commonly used for decorative purposes, such as coating jewelry with a layer of precious metal.
2. **Write a short note on electrical testers.**
- Electrical testers are devices used to check the presence of electrical voltage or current in a circuit. They come in various types, including voltage testers, continuity testers, and multimeters. These tools are essential for ensuring the safety and functionality of electrical systems.
