The relationship between current (I) and resistance (R) is given by $I = \frac{k}{R}$, where $k$ is a constant. Given $I = 8$ amperes when $R = 882$ ohms, we can find $k = I \times R = 8 \times 882$. To find the current when $R = 356$ ohms, we use the same formula with the calculated $k$, resulting in $I = \frac{k}{356}$, which gives approximately 19.8 amperes.
