Yes.
In normal house wiring, every time you plug in any lamp or appliance, you will increase the amount of current ("amperes" or just "amps") that you draw.
The circuit breakers or fuses in your house's electrical box are there to keep you from plugging so many things in that the wire gets hot enough to cause a fire.
Just to be clear however, the light bulbs do not create current. They pull current through themselves.
Bulbs (and all other electrical devices) pull electrical current in the same way that opening the water valve on your sink pulls a flow of current of water.
Your house's electrical service can be thought of as a water hose with the end plugged up. Whenever you let a little of the water flow out (i.e. ... turn on a light bulb) you create a current of water (an electrical current in the case of our light bulb).

∙ 13y agoThe resistance of the circuit increases when you add a light bulb. For the same voltage, the current will decrease as you add the light bulb. Ohms law: voltage = current x resistance.

What is an electric current flowing in only one direction?
In a series circuit, then yes, there is only one pathway. For example: if one bulb fuses, all the bulbs in the serial circuit will go out. But there are more pathways in a parallel circuit. For example: if one bulb fuses, all the other bulbs in the parallel circuit will still light.
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 are the job of the wires in a circuit?
They complete the ckt. Without wires/conductors of some sort, we couldn't connect all those other parts.They are connections between other parts of the circuit such as light bulbs, buzzers, etc. The wires carry the electricity through them to the light bulbs, buzzers, switches, etc on the circuit.
How many 75 watt bulbs can be on a 20 amp circuit?
Common sense with electrical systems dictates that current in a circuit be limited to 80% of nameplate (20A). The number of 150W lamps will be limited to 12 in this scenario. This answer can be superseded by local ordinance.
How do you wire two bulbs for one switch?
The two bulbs will be wired in parallel with each other. The switch will be wired into the circuit upstream of the bulbs.
What happens to electrical current and voltage in a parallel circuit as you add more bulbs?
Voltage remains constant; current increases.
How is the current affected by the number of bulbs?
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.
If you have three light bulbs on a circuit but all the bulbs have a different electrical path what kind of circuit do you have?
Parallel.
Which circuit has brighter bulb side by side?
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.
What does the light bulb do in a circuit?
Bulbs convert an electrical energy to produce light
This circuit is a series circuit because?
the same current flows through both light bulbs
What happens to the current measured as more bulbs added?
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.
In a series circuit what would happen if one of the bulbs stopped working?
All the bulbs will go out. In a series circuit, the current at all points is the same. This is Kirchoff's Current Law. If you loosen or remove a bulb in a series circuit, the current at that bulb becomes zero, and by Kirchoff's Current Law, the current in every part of the circuit also becomes zero.
Compare the current in a 2 light bulbs wired in a series circuit?
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).
How does light bulbs in a circuit affect the current size?
They don't unless you speaking about a parallel circuit in which total currect would be the sum of all the currents in each light bulb (The more light bulbs, the more current draw) If you're talking about a series circuit, nothing at all happens to the current, as in a seires circuit current is constant throughout the entire circuit (voltage changes). In a case such as this the more light bulbs in the circuit, the less the voltage becomes across those bulbs (furthest from the source), thus they will become dimmer due to lower power (P=IE).
What would be different about the circuit if a resistor were added in series with the light bulbs?
The total current in the circuit will decrease.
In a series circuit as more bulbs are added the bulbs get dimmer the electric current through each bulb?
By adding more light bulbs
