Physics - EM Waves Question with Solution | TestHub

The electric field through an area of $2{\mathrm{m}}^2$ varies with time as shown in the graph (time t in $\mu s$; the lowest value of E is $-1.0N/C$).

The graph has three straight-line intervals: (1) 0 to 2 $\mu s$, (2) 2 to 10 $\mu s$, (3) 10 to 13 $\mu s$.

Enter the number of the interval (1, 2 or 3) in which the displacement current through the area is greatest.
