The concept of the volt has always interested me. The volt is a "work"
function and in the MKS system is shown as "joules per coulomb". The work
done to move a charge from infinity to a point in an electrostatic field is
one joule per coulomb or one volt. How would you relate this to creating the
voltages on the secondary terminal of a Tesla coil?
