No. Although there is a voltage drop across the filament of an incandescent light bulb, the amount of current flowing out is identical to what flows in: current in = current out. That is an important fact to always keep in mind when solving simple electrical circuits: the sum of the currents flowing into a node equals the sum of the currents flowing out of it.

∙ 14y agoItgets brighter assuming it's an incandescent bulb. An incandescent light will get brighter if more current flows through it. An incandescent bulb is one with a tungsten filament. As it gets hotter the outer layers of the filament start to melt away and the bulb will eventually fail. In a halogen bulb, the same principal is used. The current id increased so much more visible light is emitted but a mechanism exists on these bulbs to redeposit the molten tungsten.

∙ 11y agoYes. A light bulb will burn brighter if you increase the current. Most especially
if you increase the current that is flowing through the light bulb.

What are the advantages of co-current flow?
A Counter-current flow has more advantages as comapared to a co-current flow.
What happens to a light bulb when extra dry cells are added on a series circuit?
i think that the light bulb glows brighter
Why is generator armature harder to rotate when it is connected to a circuit and supplying electric current?
Because a generator extracts energy from whatever is rotating it and passes this (by the electric current it produces) down the circuit to the motor (or light bulb or heater) where it is used. When there is no complete electric circuit, no electricity can flow so no (little) energy is extracted, but when the circuit is closed, electricity does flow and the armature is more difficult to turn.
Is a light bulb a simple machine?
A light bulb is a simple machine. A light bulb is a screw.A screw is a simple machine.
What would make a light brighter the Alternating Current or the Direct Current if both have the same voltage?
For the same bulb, there would be no difference if the AVERAGE power is the same. For DC this is easy....Power = V X I. For AC it is much more complicated, for a purely resistive light bulb, Power = Vrms X I. So for AC the voltage is the "root mean square" of the peaks.
When the bulb is the resistance what this tells about the resistance?
An incandescent bulb has a filament that has a resistance. The value of the resistance determines the current that will flow for a given supply voltage. The heat generated by the current flowing through the filament gives off light. As the resistance of the filament decreases the current increases and you get more light.
In an electric current electricity flow how?
Electricity can flow in an electric circuit by a battery. The battery creates electrons, which flow through the wire, and then go into a light bulb. (That is how a light bulb in a circuit lights up.) A series circuit is a circuit with one wire that electrons can flow through. Also, there can be more than one light bulb connecting to the same wire. A parallel circuit is a circuit with light bulbs that have their own wire.ClarificationThe above answer, unfortunately, perpetuates the myth that current leaves a battery, and finds its way around a circuit. This is not the case at all. It is the load that 'draws' the current from the battery and it is the load that determines the size of that current.
What consumes more power a light bulb or toaster?
By far a toaster draws more current than a light bulb.
Does a 25 watt light bulb draw more current than a 60 watt light bulb?
No, a higher wattage INCANDESCENT light bulb uses more current than a lower wattage INCANDESCENT light bulb. Some CF and LED bulbs are rated by the amount of light that an incandescent bulb would produce, but they are also rated by the wattage that they use.
What happens to the bulb when the switch is on. why?
Current begins to flow through the tungsten filament of the wire. Because of its high resistance, the wire heats up till the point that it starts glowing, producing light from the bulb.
Does current change in a circuit having bulb in series with a resistance?
Absolutely the more Resistance is put in series the less current Will flow.
How many electrons are in the filament a 100 watt light bulb?
More than I want to calculate for you right now. Also the number is the same whether the bulb is lit (current flowing) or dark (no current flowing). Also tungsten has 74 electrons, of which only 2 are in the conduction band and free to participate in current flow.
If there are more wires does the light get brighter?
No. Or at least not perceptually. The wires only supply electricity to the bulb - the bulb is what limits the current.
Why is the current in an incandescent light bulb greater immediately after it is turned on than it is a few moments later?
It need to flow through fast to make sure nothing is in the way, using more energy.
Can you substitute a regular light bulb for a krypton light bulb?
Generally, yes. It will all depend on the voltage and the current capabilities of the supply. Mostly in torches (flashlights), you can. Using a krypton bulb wil be brighter but draw more current, reducing the life of the batteries.
Is it more difficult for current to flow through a circuit with two bulbs than with one?
yes because of bulb resistance :)
How do you use electric light bulbs?
This is a somewhat an open type of question with a general scope. I have to believe that there is more to the question?One uses light bulbs by applying voltage to their contacts, this causes a current flow through the bulb and depending the the specific bulb type (incandescent, fluorescent, LED, etc) the internal components (filament, gases, LED's, etc.) create light.
