18-9 Microscopic View of Electric Current

18-9 Microscopic View of Electric Current. Electrons move about in a wire much like gas molecules…they bounce off of each other and metal atoms. They ‘feel’ an electric field that accelerates them, but they eventually reach a moderate drift speed.

Presentation Transcript

  1. 18-9 Microscopic View of Electric Current Electrons move about in a wire much like gas molecules…they bounce off of each other and metal atoms. They ‘feel’ an electric field that accelerates them, but they eventually reach a moderate drift speed. The electrons pass through a distance l with a velocity v in a time t….. l=vdt I=Q/t=neAvd See Example 18-13 p545

  2. 18-10 The Nervous System and Nerve Conduction • See Diagram and chart p 546 & 547 • See Example 18-14 p548
