Answer
Let's address each question one by one:1. Which term describes a device that provides the electrical energy in a circuit? - A. load - B. switch - C. energy source - D. conductor **Answer: C. energy source**2. Which symbol represents an electric cell? - a.  - b.  - c.  - d.  **Answer: The correct symbol for an electric cell is typically represented as two parallel lines, one longer than the other. Without the actual symbols provided, I cannot definitively choose the correct option. However, if you have access to the symbols, look for the one with a long line (positive terminal) and a short line (negative terminal).**3. Which symbol represents a lamp? - a.  - b.  - c.  - d.  **Answer: The correct symbol for a lamp is usually represented as a circle with a cross inside it. Again, without the actual symbols provided, I cannot definitively choose the correct option. Look for the symbol that matches this description.**4. Which circuit diagram represents a series circuit? - a.  - b.  - c.  - d.  **Answer: A series circuit is characterized by components connected end-to-end, forming a single path for current flow. Without the actual diagrams provided, I cannot definitively choose the correct option. Look for the diagram where all components are connected in a single loop.**If you can provide the actual symbols or diagrams, I can give more precise answers.
