Why do light bulbs get brighter when you attach more batteries to it?
More power
What will happen to a bulb if you add more batteries to a simple circuit?
It gets brighter and brighter - until it burns out.
How does the amount of energy in the batteries compare to the total amount of light given off by the flashlight?
Well more chemical energy in a battery means more energy can be converted to light energy. I believe that the light will last longen and\or be brighter.
Which bulb will glow brighter with 220V - 40W or 400W?
-- The voltage makes no difference. -- The 400W device dissipates ten times as much power as the 40W device does. We don't know how much of each one's power consumption is radiated in the form of heat, UV light, etc. But if the spectral distribution of their output is similar, then the one that dissipates more power produces more visible light, and appears brighter.
How could you make a light bulb in a circuit brighter?
-- Without changing the bulbs, increase the voltage of the battery or power supply. -- If the bulbs are in series, take one out of the circuit, and replace it with a piece of wire. -- Replace incandescent bulbs with others whose filaments have lower resistance. -- Replace incandescent bulbs with fluorescent tubes. -- Replace incandescent bulbs with LEDs.

What is true about a sound wave?
In science when you have light and you put more batteries to it have a brighter light and more energy

Which is the brighter - the light coming in or the light from the flashlight?
Sun light is more brighter than the light from flashlight in house.
Which is brighter the light coming from in or the light from the flashlight?
Sun light is more brighter than the light from flashlight in house.
Can you make a bulb glow more brightly by adding a second battery?
Yes, two batteries will make a light bulb brighter than one, provided that the batteries are placed in series. The brightness of the bulb is determined by the voltage, and placing two batteries in series rather than just using one increases the voltage.
Can you make more sun light out of less sun light if you had a little sun light coming though a hole could you make it brighter?
No. That would violate the laws of physics.
What is the effect of changing the numbers of batteries in a circuit?
Before we can attempt an answer to that question, we'll need to agree on themeaning of the fuzzy, slippery phrase "amount of electricity". I'm going to interpretthat phrase to mean the current through the circuit.If the batteries are connected in series, then more batteries produce more currentthrough the circuit.If the batteries are connected in parallel, then the number of them has no effecton the magnitude of current through the circuit. But whatever the current is, morebatteries will cause it to flow in the circuit for a longer time, before they run down.
Is Venus's or Mars brighter?
Venus is much brighter than Mars. Only the Moon and the Sun are brighter than Venus.
Why is a bulb brighter when it is powered by 2 batteries rather than 1?
it has more energy than one bulb
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.
