What will happen if this 4.5 v bulb is connected to a 1.5 v cell?
The bulb need the correct voltage to operate. Your bulb would light if it is a 1.5 volt light. So the voltage of the supply and the light must be matched. Too little voltage won't light the light, too much will light it too much and blow it up.
How do you make a bulb which glow on your clapping bulb?
you have to need IC 3 ,bulb
What do you need to make a light bulb glow?

How do you wire a high watt light to a battery?
Need more information. Wattage of bulb, voltage of bulb, voltage of battery and wire size of the circuit.
How many volts does a fluorescent light bulb need?
The correct voltage should be printed on the light bulb.
What is the voltage of a dlp lamp?
About 5000 volts. Additional Explanation of this answer While the "Striking Voltage" of the Bulb may be 5,000 + volts the bulb actually operates on much less. More like 120V or 200V. If you continued using 5,000 V the bulb would rapidly burn itself out. The striking voltage is much like a Florescent bulb. The higher voltage is to cause a spark between the gaps or electrodes to ignite the gasses within the bulb regardless of Florescent , High Pressure Mercury or any similar bulb, then the voltage lowers to keep the bulb lit. This is exactly the reason they need a Ballast, Starter or similar device to start the bulb Hopefully this answer helps others We decided to edit the other persons answer to further explain and to help avoid and injuries or damages caused by improper voltage Electronic Surplus Div or Replacement Tv Parts
What size resistor do you need to power a 14 volt bulb from a 120 outlet?
To find the resistance necessary, one would need to know how much current the bulb draws. If one knows the current the bulb draws, then one would subtract the 14 volts from 120 volts then divide that by the current the bulb draws and one will find the resistance needed. Once this has been done, one would need to multiply the current drawn by the voltage drop to get the wattage rating necessary. Another important detail to note is that the power dissipated by the resistor will be much greater than the power consumed by the bulb itself. Finally if the bulb burns out the voltage across the contacts will be 120V. I would not recommend using this method to drop the voltage for the bulb.
WHAT IS THE LOWEST VOLTAGE NEED TO LIGHT A LIGHT BULB?
A light bulb is manufactured to operate on a specific voltage. The voltage can be a low as needed and the manufacturer will compute the size of the filament that is needed for a specific wattage. If you are referring to a threshold voltage then that is another question that needs to be asked.
What kind of battery do you use to make a light bulb glow using wire and battery?
Any sort of dry battery will do this, you just need to match the required bulb voltage with the battery voltage. Most small dry batteries give 1.5 volts, the square shaped ones give 9 volts, and there are bigger ones used for lanterns and large flashlights. The bulb should have on it the required voltage, if it is say 3 volts you will need two batteries in series (connect them positive end to negative end of the second) or you can make a string in series, you just get number of batteries x 1.5 volts. If it is a car bulb these operate at 12 volts, you will need a car type battery for these.
What 2 things do you need for a current to flow?
Potential difference and the conductor. A cell and a bulb. Some connecting wires. The bulb can be made glow by connecting the wires with the cell.
What voltage does an led bulb need?
Minimum 2V. Some can run as high please check sheerled.co.uk/
Do you need a battery to light a light bulb in a circuit?
Yes as long as the battery and bulb are rated at the same voltage. (Boy Scouts do it every day with flashlights.)
