Question

The difference between bulbs connecting in a series ciciut and parallel circuit?

Answer 1

When you connect bulbs in series, you are splitting the voltage that goes to each bulb. So if you have a 12V battery and two 6V bulbs, this is just what you want... each bulb will get about half of that voltage. But if you had two 12V bulbs, the voltage split would result in a much dimmer light from each of them.

In parallel, you split the current to each one. Since the current is usually determined by the bulb, this will actually mean your circuit draws twice the current as it would with a single bulb, unless your circuit has a current limit. When you parallel two 6V bulbs on that 12V battery, they probably burn out. But with two 12V bulbs, each will hit full brightness, as long as you have enough current to feed both bulbs.
