Unformatted text preview: of electrons What What really happens is quantum mechanical – like covalent bonding. nuclei Shared electron cloud Physics 122 Conduction In In a crystal of a metal, all the atoms are bonded and some electrons shared. You You can think of some of the electrons as running in each direction along the chain. When an electric field is put on the chain, is shifts the balance and more electrons go one way than the other. Physics 122 Dr. Nick Cummings 3 Physics 142 7/26/2011 How to think about current? Unless Unless we are going to be materials science physicists, we don’t really need to understand the quantum view of conduction. Instead, Instead, we construct a bunch analogies that have some of the correct features. – water flow – air f...
