I have a variable transformer, http://www.faqs.org/docs/electric/AC/02149.png

If the current in the load (set in the middle at say 120 volts) is 3 amps, I assume the current from the source (240 volts) will be 1.5 amps. Does this mean that the current in half the windings is 4.5 amps (3 plus 1.5), or 1.5 amps (3 minus 1.5), or will the load current be out of phase with the source?
