Answer #1

The equation you need to solve this problem is:

\(i=\frac{Q}{t}\)

\(i=\frac{2.5 \mathrm{C}}{(0.0002 \mathrm{~seconds})}=12500 \mathrm{Amps}\)

sig.figures : \(i=13000\) Amps

Note: If you are using an online homework submission system you may need to account for significant figures. Since there are only 2 significant digits, you may need to round your final answer to 13,000 Amps
