Answer

I = 2.43 \, \text{A} Explanation 1. Convert units Convert charge from mC to C: 75.6 \, \text{mC} = 75.6 \times 10^{-3} \, \text{C}. Convert time from ms to s: 31.1 \, \text{ms} = 31.1 \times 10^{-3} \, \text{s}. 2. Calculate current Use the formula for current: **I = \frac{Q}{t}**, where Q is charge and t is time. Substitute Q = 75.6 \times 10^{-3} \, \text{C} and t = 31.1 \times 10^{-3} \, \text{s}.

Explanation

1. Convert units<br /> Convert charge from mC to C: $75.6 \, \text{mC} = 75.6 \times 10^{-3} \, \text{C}$. Convert time from ms to s: $31.1 \, \text{ms} = 31.1 \times 10^{-3} \, \text{s}$.<br /><br />2. Calculate current<br /> Use the formula for current: **$I = \frac{Q}{t}$**, where $Q$ is charge and $t$ is time. Substitute $Q = 75.6 \times 10^{-3} \, \text{C}$ and $t = 31.1 \times 10^{-3} \, \text{s}$.
