190- The graph of a sinusoidal alternating current is shown below. What is the value of the current at the moment $t = \dfrac{1}{3200}\,\text{s}$?
[(1)] $2.5$
[(2)] $2.5\sqrt{2}$
[(3)] $5$
[(4)] $5\sqrt{2}$
[Figure: Graph of $I\,(\text{A})$ vs $t\,(\text{s})$. The current is sinusoidal with amplitude $-5\sqrt{2}$ (minimum shown on $y$-axis) and period marked at $t = \dfrac{1}{320}$ on the $x$-axis.]
