How many light bulbs can a 6 volt battery light up?

If the type of light bulb you are using was made to run on 1.5 volts, a 1.5 volt battery should be able to light up one or several of those types if they are each wired in parallel directly across the 1.5 volt battery.If the type of light bulb you are using was made to run on 0.75 volts, a 1.5 volt battery will light up two or more of those types if they are wired in pairs in series across the battery.If the type of light bulb you are using was made to run on, say, 3.0 volts, a 1.5 volt battery will not light it up very much - it may just glow dimly.If the type of light bulb you are using was made to run on any voltage higher than, let's say 5 volts - for instance a standard 120 volt household bulb - then your 1.5 volt battery will not be able to light one of those up at all.Another answerYou can wire any number of 1.5v bulbs in parallel, but for each one you add you will draw more current. Draw too much current and the battery will get hot and may explode, depending on what it is made of.How long the battery will be able to keep the light bulbs lit will depend on the size of the battery, meaning how much charge it can hold. (Its capacity in amp.hours.)
