Expert Solution
Step 1: Given data

Potential difference or voltage is V equals 3.12 space nV

Length of copper wire is L equals 2.31 space cm

Radius of wire is r equals 2.01 space mm

Time is t equals 3.32 space ms

Resistivity of copper is rho equals 1.69 cross times 10 to the power of negative 8 end exponent space straight capital omega times straight m

Note:

1 space straight m equals 100 space cm

1 space straight V equals 10 to the power of 9 space nV

1 space straight m equals 1000 space mm

1 space straight s equals 1000 space ms

Find:

The amount of charge drfit through cross-section in given amount of time.
