Wiring bulbs in a series is useful in certain applications. For example decorated lighting on holiday trees using multiple bulbs on a single circuit. This is useful by keeping the circuit linear and simple and allows for a single switch. The disadvantages to having multiple bulbs on a linear circuit is that if one bad bulb turns off the whole circuit.

∙ 9y agoThe effect of adding bulbs to a circuit that is connected in series is that it increases the load. As such, the bulbs will become dimmer with each addition since the bulbs share the current flowing through the circuit.

∙ 12y agobeacause copper is what is used in wires and when wiring series, less copper wire used which means cheaper. houses today usually have parallel circuits. trust me, i teach technology at a school.
CommentIf you teach technology, then you should know that there is absolutely no reason why connecting lamps in series, rather than in parallel, would necessarily require less copper. Furthermore, the disadvantages outweigh the advantages. If any lamp fails, then the entire circuit will fail. An empty lampholder will be subject to the full supply voltage and, so, present a shock hazard. All lamps must have identical power and voltage ratings.Add your answer:

If you add an extra bulb to your series circuit what will happen to the brightness of the bulbs?
The bulb is dim.Because,the voltage is drops in series connection so you add more bulbs in series the last bulb got low voltage that reason for the bulb is dim
Will the current increase if you add more bulbs to a series circuit?
A: In a series path anything added makes current to go down assuming the source remain the same
What will happen to the current if you add more bulbs to the cirrect series?
current will decrease
What happens when you add a resistor to a series circuit with a light bulb?
As you add more bulbs to a series circuit that means that the bulbs are in series to one another, therefore the total resistance is the sum of the individual resistance of the bulbs. If you add bulbs of the same resistance,then the rate at which the resistance changes will increase in a constant manner provided the current source is not altered. For instance if the bulb you are using is rated 20v,60w, then the current passing via the bulbs in series is the square of the voltage divided by the power in this case the current is approximately 7amperes.
10 ohms 60 ohmsand 50 ohms are wired in series and connected to a 120-V battery What is the equivalent resistance for this circuit?
For a series circuit such as this, simply add the resistances to get the equivalent resistance.For a series circuit such as this, simply add the resistances to get the equivalent resistance.For a series circuit such as this, simply add the resistances to get the equivalent resistance.For a series circuit such as this, simply add the resistances to get the equivalent resistance.

The current is 0.4 A and the bulb in the circuit is bright. What will happen to the brightness of the bulb if you put another bulb in series in the circuit?
ANSWER: The brightness of both bulbs will decrease. If the bulbs are identical the current will decrease to 0.2 Amps. This is a simple series resistive circuit, the more bulbs you add in series both the amperage and bulb brightness will continue to go down.

What is the difference between parallel circuit lights and series circuit lights using the idea of current flow?
Parallel circuit lights are built as so: ______light_______ |_____light_______| |_____battery_____| Series circuit lights are built like this: ___light___light___battery___ |________________________| In a parallel circuit, lights don't get dimmer when you add more, and if one breaks, the others still work. In a series circuit, when you add more, the lights get dimmer, and when one breaks, they all break. It is possible to have a combination of both in one circuit though.

What happens to the current if the number of bulbs stays the same but you use more cells?
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.
What happens if you add 2 light bulbs to a simple circuit?
A: There is no such a thing as simple circuit if the bulbs are put in series the light will dim if put in parallel both bulbs will light up the same provided the source can sustain the power increase

What happens to electrical current and voltage in a parallel circuit as you add more bulbs?
Voltage remains constant; current increases.
How do you add a switch to a series circuit?
usually in series
How can you make a current smaller in a circuit?
Taking some bulbs out of the circuit!! (I think :P) Taking some bulbs out of the circuit!! (I think :P) Use Ohm's law I = E/R. Add some values and check it out. You use the formula V = IR (where V and E are the same thing, voltage. I is the current. R is the resistance). If you add more resistance then your current will be lower. I would suggest looking at parallel and series resistance so that you can understand equivalent resistance.
