AP Physics C: E&M
11.1 Electric Current
BeginnerMCQGraphicalMathematical18.4k
A line graph plotted on a Cartesian plane. The horizontal axis is labeled t in seconds with tick marks every 1 second from 0 to 6. The vertical axis is labeled q in Coulombs with tick marks every 2 units from 0 to 14. The plot consists of three connected line segments: the first starts at (0, 0) and rises linearly to (2, 12); the second is horizontal from (2, 12) to (4, 12); the third decreases linearly from (4, 12) to (6, 4). No other lines or labels appear.
Net charge q versus time t
The graph shows the net electric charge \(q\) that has passed through a cross section of a wire as a function of time \(t\). What is the magnitude of the electric current through the wire during the time interval from \(t = 4\text{ s}\) to \(t = 6\text{ s}\)?
