parallel circuit

I learnt that in a parallel circuit the voltage across each component will always remain the same, but the current through each of the circuits may be different. that's because the current is being shares between components. we did this by measuring the available voltage from two bulbs which was 11.91 from the first bulb and 11.91 from the second bulb and than we measured the voltage drop across each light bulb. the results was bulb one 11.78v and 11.80v. the current flow was bulb one 0.73 and bulb two was 0.71 which adds up to 1.44 and that's because the current was all shared between  them.
