Not quite. Using ohm's law, at 110V, the 10A load has 11 ohms resistance. The 1A load has 110 ohms resistance. Assuming the resistance doesn't change (not true with light bulbs since the resistance depends on temperature and therefore power...), if the neutral opens,
we now have 110 ohms in series with 11 ohms
(121 ohms) across 220V. In that case the current in either is 1.82A. The 10A load will see 18.2 volts across it and the 1A load will see 182V across it, until it blows.
