Question

State a rule for how the current into the junction should compare to the current out of a junction.

Hint:

It's okay if your rule isn't perfect! In the next section, you'll have a chance to try another circuit and refine your rule.

### Electrical Currents in Junctions

**Description of Junctions and Currents**
- These junctions have two currents entering and one current leaving.
- The red arrows indicate the currents going into the junction C.
- The green arrow indicates the current leaving junction C.

**Recording Currents at Junctions**

We need to observe and record the currents into and out of these junctions as detailed in the table below.

| | Junction | Current In | Current In | Current Out |
|----------|----------|------------|------------|-------------|
| | | A | I | A | I |
|----------|----------|------------|------------|-------------|-------|
| 1 | C | 0.90 | 0.90 | 1.80 |
| 2 | D | 0.90 | 0.90 | 1.80 |

---

- *Junction C*: Two currents of 0.90 amperes each are entering the junction, making the total current entering 1.80 amperes. The current leaving the junction is also 1.80 amperes.
- *Junction D*: Likewise, two currents of 0.90 amperes each are entering the junction, making the total current entering 1.80 amperes. The current leaving the junction is also 1.80 amperes.

**Explanation of Diagram**
- The diagram displays junctions with currents represented by arrows.
- **Red Arrows:** Currents entering the junction.
- **Green Arrow:** Current leaving the junction.

This information is important to understand how currents flow through electrical circuits, specifically at junctions where multiple currents meet.

### Explanation of Current Flow at Junctions

Each of these junctions should have one current going in and two currents going out. The red arrow in the diagram shows the current going into junction A, and the green arrows show the currents leaving junction A.

#### Diagram Explanation

The diagram illustrates a junction (labeled A) where the red arrow points towards the junction, indicating the incoming current. Two green arrows point away from the junction, representing the outgoing currents.

#### Data Table: Currents at Junctions

Below is a table recording the currents into and out of these junctions:

| Junction | Current In (A) | Current Out (A) | Current Out (A) |
|----------|----------------|----------------|-----------------|
| A | 1.80 | 0.90 | 0.90 |
| B | 1.80 | 0.90 | 0.90 |

**Note:** All currents are measured in amperes (A).

This setup ensures the principle of conservation of current at each junction, where the total current entering a junction equals the total current leaving that junction.
