A current of 1.00 A flows in an aluminum bar which is 10.0 cm long and 1.00 cm square sides. If electrons drift through the bar at a speed of 3.50×10−7 m/s, how many free conduction electrons are in the bar at any moment? 3.31×1022 7.00×1029 1.78×1024 1.79×1029

A current of 1.00 A flows in an aluminum bar which is

10.0 c m

long and 1.00

c m

square sides. If electrons drift through the bar at a speed of

3.50 \times 10^{- 7}

m / s

, how many free conduction electrons are in the bar at any moment?

3.31 \times 10^{22}

7.00 \times 10^{29}

1.78 \times 10^{24}

1.79 \times 10^{29}
