## Electrical Circuits Educational Exercise

### 1. Sketch a correct circuit diagram that corresponds to the following:
#### a. Draw diagram here: [ X / 5 ]

**Description of the diagram:**
- **Components:**
  - **Battery:** Represented as a cylinder on the left side of the diagram.
  - **Switch:** Shown as a breakable line segment in the upper right part of the circuit.
  - **Wire:** Depicted as lines connecting the components.
  - **Light Bulb:** Illustrated as a bulb symbol on the right side of the diagram.

**Diagram Explanation:**
The battery is connected in a series circuit with a switch and a light bulb. The circuit forms a closed loop where electrical current can flow from the battery, through the switch, and into the light bulb, lighting it up when the switch is closed.

#### b. A battery is connected to 4 light bulbs in parallel to each other. Draw diagram below: [ X / 5 ]

**Diagram Explanation:**
For this problem, students are required to draw a parallel circuit. In a parallel circuit, each light bulb will have its own direct path to and from the battery. This means if one bulb burns out, the other bulbs will continue to operate.

**Important Aspects for the Diagram:**
1. **Battery:** Should be positioned to supply power to the entire circuit.
2. **Light Bulbs:** Four bulbs should each be connected in parallel to the battery.
3. **Connecting Wires:** These should run from the positive terminal of the battery to each bulb and then return from each bulb to the negative terminal of the battery.

**Note:** The diagram should emphasize that the voltage across each light bulb in a parallel circuit is the same, and current will divide among the parallel branches.

**Page 1 of 4**

This layout and instruction set helps students understand the differences between series and parallel circuits by visual representation and provides a clear expectation for diagram drawing in an educational setting.

### Electrical Circuits Quiz

#### Question 2

**Identify the following circuits as being in series or parallel. Explain how you know. [X / 8]**

**Diagram Explanation:**

- **Circuit 1:** 
  - The image shows three light bulbs connected in a single line, one after the other, to a power source. This configuration is indicative of a series circuit, where components are connected end-to-end in a single path for current to flow.

- **Circuit 2:**
  - The image displays three light bulbs each connected to a separate path that then connects back to the power source. This is typical of a parallel circuit, where components are connected across common points or junctions, providing multiple paths for the current to flow.

**Answer Boxes:**

- **Circuit 1:**
  * (Blank space for detailed student explanation) *
- **Circuit 2:**
  * (Blank space for detailed student explanation) *
  
#### Question 3

**For the diagram below, a current of 6 A flows through the circuit. Find the resistance and power in the circuit. [X / 10]**

*Note: The diagram related to Question 3 is not visible in this image.*

**Answer Boxes:**

- **Total resistance:**
  * (Blank space for student calculation and answer) *
  
- **Power:**
