If the voltmeter reads 3V what will the voltage be across each bulb?

Hi Moon, if it’s 3V at the battery with ONE bulb it’s 3V - the same! If it’s TWO bulbs it’s half 1.5V. If it’s THREE bulbs it’s a third -1V. FOUR bulbs divide by 4, so 1V. (In a parallel circuit it would be 3V for every Bulb on each branch, if there’s more than one bulb on each branch it shared like above) Hope that helps!
