As the number of bulbs in a series circuit increases, the current decreases. As the number of bulbs in a parallel circuit increases, the current increases.
The line current increases when more bulbs are switched on in parallel, since more parallel current paths results in lower effective resistance. The line voltage should not change in response to any normal use of electric power in a single house.
yes because of bulb resistance :)
A: Adding any resistance bulbs or whatever in a series circuit will reduce current and will reduce total power. In this case the bulb will glow dimmer as any additional bulbs are placed in the series circuit. this is true if the same input source is kept constant.
Electric current is that current which generate from electric voltage . it flows on your induction motors also on your computer and your television set's cord and every where which device is operate by electricity. doesn't matter what instrument you are operating. it will flow.
Because the total current is divided between the two components. For example, if the current was one amp, and you connected two bulbs in series, ech bulb would get half an amp of current. As brightness is proportional to current, this means they glow more dimly.
If you add more cells in series with the bulbs, the current will increase as the voltage across the bulbs increases. If you add more cells in parallel with the bulbs, the current will stay the same because the voltage of the cells does not increase when they are added in parallel.
Assuming the bulbs are identical, the voltage drop across each one is inversely proportional to the number of bulbs. So, for example, 240V could power 20 12V bulbs in series. In addition, the circuit would have to be able to supply the necessary current.
Since the SAME electrons have to go through both light bulbs, the current in both light bulbs will be the same (Kirchhoff's current law).
If a circuit is wired in parallel, all the bulbs have their own independent access to electricity, so if one bulb goes out, the others are not affected. If the circuit is wired in series, then one bulb going out will block the current to all the other bulbs as well.
No. Bulbs use energy, they don't provide it.
current consumtion of a bulb
current will decrease
It is unclear what type of circuit you are referring to, so I'll give both answers.parallel, current increases until too many bulbs have been added, then circuit breaker pops and current drops to zero.series, current decreases and all bulbs dim.
The bulbs get progressively darker. Electricity is the flow of electrons and the potential difference caused by these electrons powers the bulbs. The first bulb will get the most amount as the electrons flow past, then the 2nd will less and so on for any other bulbs in the series.
By adding more light bulbs
Temperature and salinity
Bulbs in a parallel circuit draw the same amount of current, so each will display the same brightness. Bulbs in a series circuit share the current so all bulbs will appear dimmer.
