Answer

To determine the charge flow in the wire, we use the formula:

extchargeflow=extcurrentimesexttime ext{charge flow} = ext{current} imes ext{time}

Where:

  • Current = 5.0 A
  • Time = 2 minutes = 120 seconds

Now substituting in the values:

extchargeflow=5.0extAimes120exts=600extC ext{charge flow} = 5.0 ext{ A} imes 120 ext{ s} = 600 ext{ C}

Thus, the charge flow in the wire is 600 C.
