AP Physics 2
11.1 Electric Current
BeginnerMCQGraphicalMathematical15.1k
A quantitative line graph showing electric charge Q in coulombs versus time t in seconds. The horizontal axis represents time t from 0 to 8 seconds with major tick marks every 1 second. The vertical axis represents charge Q from 0 to 18 coulombs with major tick marks every 3 units (0, 3, 6, 9, 12, 15, 18). A solid black line begins at the origin (0, 0) and increases linearly to the point (5, 15). From (5, 15), the line continues horizontally to the point (8, 15). Grid lines extend across the plot area for easy reading. No other labels, lines, text, or axes appear.
Charge vs. time for a wire cross-section.
The graph shows the net electric charge \(Q\) passing through a cross-section of a cylindrical conducting wire as a function of time \(t\). What is the electric current flowing through the wire at time \(t = 3 ext{ s}\)?
