Re: current flow

[Wabbot@domain.elided]

When I was in college I had two different electronic classes.  One professor 
talked electron flow and the other talked hole flow.  Show the same circuit 
to each professor and ask which way is the current flowing and you got two 
different answers.

When I owned a 63 Triumph TR4 with a positive ground system Radio Shack sold 
a converter which would attach to the positive ground system of your car.  
Internally it would generate a current 12 volts above the positive ground.  
You could then connect a negative ground device such as a radio to the output 
of the converter by connecting the ground to the chassis and the positive to 
the output of the converter.  I still have it around the garage someplace.
