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.

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.
What consumes more power a light bulb or toaster?
By far a toaster draws more current than a light bulb.
Is current greater in electric iron or in bulb?
A running iron uses the same power as nine 100 watt bulbs.In the home, depending upon where you live, the service voltage is fixed at either 110 or 220 volts. Various appliances and devices require different amounts of energy, of course. Since the voltage (or pressure of delivery) is the same, the current (volume of delivery) is what changes.In round numbers, a clothes iron might draw 10 amperes of current at 110 volts, or 1100 watts of power. A light bulb might draw 1 ampere of current at the same voltage.It's easy to see that the iron will draw far more current than even an inefficient incandescent light bulb.
What consumes more power a light bulb or a refrigerator when they are on?
Refrigerator- it takes more power to kick on and it pulls more electricity than a light bulb
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.

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.
Which 12 volt bulb will draw the most current when connected to a 12 volt battery?
The bulb with the lowest resistance. Current = Volts / Resistance

Does more current flow into a light bulb than out of it?
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.
How is the early light bulb changed by the modern light bulb?
The early light bulb used a rather powerful electric current, Did not have a very good vacuum inside it and in some did not use a bulb at all! Today's light bulbs use less electricity and have no oxygen inside them. This makes them more efficient and reliable.
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.
Why wont your car CD players LED light not turn off when the car is not on?
Residual current in the circuit which is insufficient for a normal bulb to work. LEDs need very little current, hence may still show as on. If you look closely you should see the LED not at full brightness, it draws very very little current and should not drain a battery. You can fit a resistor, but that would draw more current than a conventional bulb.
When electric current flows through a light bulb electric energy is formed to what?
It is converted into heat and light. Different types of bulb produce more light than others for the same power. Incandescent bulbs are the worst, fluorescent the best.
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).
In a series circuit as more bulbs are added the bulbs get dimmer the electric current through each bulb?
By adding more light bulbs
