# A central junction in an electric circuit connects five branches carrying current, as shown in the table.

| Branch | Current Magnitude | Direction Relative to Junction |
|—|—|—|
| 1 | \(3\text{ A}\) | Into junction |
| 2 | \(5\text{ A}\) | Into junction |
| 3 | \(2\text{ A}\) | Out of junction |
| 4 | \(4\text{ A}\) | Out of junction |
| 5 | \(I_5\) | Unknown |

Based on conservation of electric charge, what are the magnitude and direction of current \(I_5\)?

A central junction in an electric circuit connects five branches carrying current, as shown in the table.

| Branch | Current Magnitude | Direction Relative to Junction |
|---|---|---|
| 1 | \(3\text{ A}\) | Into junction |
| 2 | \(5\text{ A}\) | Into junction |
| 3 | \(2\text{ A}\) | Out of junction |
| 4 | \(4\text{ A}\) | Out of junction |
| 5 | \(I_5\) | Unknown |

Based on conservation of electric charge, what are the magnitude and direction of current \(I_5\)?

- **A.** \(2\text{ A}\), directed into the junction
- **B.** \(4\text{ A}\), directed out of the junction
- **C.** \(2\text{ A}\), directed out of the junction
- **D.** \(14\text{ A}\), directed into the junction
