Charge:

$\overline{){\mathbf{Q}}{\mathbf{=}}{\mathbf{i}}{\mathbf{t}}}$

Current density:

$\overline{){\mathbf{J}}{\mathbf{=}}\frac{\mathbf{i}}{\mathbf{A}}}$

**A)**

Substituting the given values to the charge equation:

Q = (170)(0.670) = 113.9C

A)How much charge passes through the starter motor? (C)

B)How far does an electron travel along the wire while the starter motor is on? (mm)
