Charge density of copper
WebThe free charge density in copper is 1.81 x 10" C/m'. For a current Question Transcribed Image Text: The free charge density in copper is 1.81 x 1010 C/m³. For a current density of 8 × 10° A/m², find the electric field intensity E and the drift velocity u. (take the electronic charge as e = -1.6 x 10-19 C and copper conductivity o= 5.8 x 107 S/m). WebSuppose we have a copper wire 1 mm in diameter carrying a current of 1 amp. One amp is one coulomb per second, so that means we have 6:2415 1018 electrons per second passing a given point in the wire. Given the charge density, we can work out the linear charge density in the wire. A centimetre length of the wire has a volume of ˇ(0:05)2 =7:854 ...
