A 100 watt bulb will normally glow brighter than a 50 watt bulb as long as you are comparing similar style bulbs. You have to compare Incandescents to Incandescents, Fluorescent to Fluorescent, LED to LED, and so forth. You also have to make sure your bulbs are similar in light patterns since you can have general dispersion lighting, spot lighting, flood lighting, and so forth. So, once again as long as you are comparing like style bulbs, yes a 100 watt bulb is brighter than a 50 watt bulb.
The 100-W bulb because it transforms electrical energy at a faster rate than a dimmer bulb.
That depends on so much more then just the watt of the bulb, but if you have two identical bulbs where the only difference is the amount of watt, then logic dictates that 25watt is brighter then 10watt
Depending on the length of the wire difference between the shot and long wire, in technical fact the bulb would be brighter if a shorter wire was used, but not that much brighter. Energy is used up as it travels along wires.
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.
Original answer: Because it gives off more power. Updated answer: In general, because the 100-watt bulb produces more total light (lumens) because it also consumes more power than the 60-watt bulb. However, a 60-watt can produce more lumens than a 100-watt bulb, depending on the types of bulbs in question.
The 2 bulb series circuit , a 3 bulb series circuit will increase resistance and therefore reduce the voltage across the bulb. The current in all points of the circuit will remain the same according to Kirchhoff.
The Shorter the wire the brighter the bulb ! Because if it is short then it get brighter and the more batterie the brighter the bulb ! Or the lower voltage the brighter the bulb !
When a bulb is attached to a battery or a cell as scientists call it, the bulb glows. If you want a bulb to glow more and more brighter, it depends on how many batteries you attached to the bulb. If you attach a lot of batteries at the same time, the bulb might even explode or burn out. The wires that hold the interaction between a light bulb and the battery is electricity. The electricity flows through the wires and touches the bulb and that is how a light bulb glows.
more battery's or a better bulb.
Yes. A 60W bulb has a higher resistance than the 40W buld. The extra resistance requires more current to light up the bulb. The fillament then glows brighter.
It gets brighter and brighter - until it burns out.
That does not depend directly on the brightness of the bulb, it depends on the current drawn by the bulb (which depends on the efficiency of the bulb). For example an incandescent bulb will draw much more current than a much brighter CFL bulb or LED bulb. Therefor switching to an brighter LED bulb can make the battery last much longer while switching to a brighter incandescent bulb will make the battery run down quicker.
it has more energy than one bulb
No. Or at least not perceptually. The wires only supply electricity to the bulb - the bulb is what limits the current.
Sounds like it's getting more current.
That depends on so much more then just the watt of the bulb, but if you have two identical bulbs where the only difference is the amount of watt, then logic dictates that 25watt is brighter then 10watt
We did this experiment in class, the more batteries added, the brighter the bulb will become!
It is probably a 60 watt bulb (believe it or not). Bulbs are rated in watts. A 100 watt bulb is brighter and consumes more power than a 60 watt bulb
