# The electric current \(I\) passing through a semiconductor device as a function of time \(t\) is given by \(I(t) = bt^2 + I_0\), where \(b = 3.0 \text{ A/s}^2\) and \(I_0 = 2.0 \text{ A}\). What is the average current passing through the device during the time interval from \(t = 0\text{ s}\) to \(t = 2.0\text{ s}\)?

The electric current \(I\) passing through a semiconductor device as a function of time \(t\) is given by \(I(t) = bt^2 + I_0\), where \(b = 3.0 \text{ A/s}^2\) and \(I_0 = 2.0 \text{ A}\). What is the average current passing through the device during the time interval from \(t = 0\text{ s}\) to \(t = 2.0\text{ s}\)?

- **A.** \(6.0 \text{ A}\)
- **B.** \(8.0 \text{ A}\)
- **C.** \(12 \text{ A}\)
- **D.** \(14 \text{ A}\)
