# Problem: RC Circuit Analysis After the switch is closed, does the current through the resistor increase, decrease or stay the same?

###### FREE Expert Solution

The charging current for a capacitor:

$\overline{){\mathbf{I}}{\mathbf{=}}\frac{{\mathbf{V}}_{\mathbf{b}\mathbf{a}\mathbf{t}\mathbf{t}\mathbf{e}\mathbf{r}\mathbf{y}}}{\mathbf{R}}{{\mathbf{e}}}^{\mathbf{-}\mathbf{\left(}\mathbf{t}\mathbf{/}\mathbf{R}\mathbf{C}\mathbf{\right)}}}$

The current decreases exponentially toward zero. That is, e-∞ = 0.
