# A constant direct current of \(1.6 \text{ A}\) flows through a uniform cylindrical wire. The wire is connected to a DC power supply for a duration of \(5.0 \text{ s}\). How many electrons pass through a given cross-section of the wire during this time interval?

A constant direct current of \(1.6 \text{ A}\) flows through a uniform cylindrical wire. The wire is connected to a DC power supply for a duration of \(5.0 \text{ s}\). How many electrons pass through a given cross-section of the wire during this time interval?

- **A.** \(5.0 \times 10^{19}\)
- **B.** \(8.0 \times 10^{19}\)
- **C.** \(1.3 \times 10^{20}\)
- **D.** \(3.0 \times 10^{21}\)
