There is another way of determining total resistance in a parallel circuit
... An alternating current source produces currents that flow in one direction and then the other, continuously cycling from positive to negative, and back. Each time current direction reverses, the direction of the magnetic field reverses. Since current alternates continuously, the magnetic field is ne ...

... As a result the different nuclear spin states have different energies in a non-zero magnetic field. In hand-waving terms, we can talk about the two spin states of a spin ½ as being aligned either with or against the magnetic field. If γ is positive (true for most isotopes) then m = ½ is the lower en ...
