That all depends in the resistance of the filament in the bulb there is not enough info in the question

How much voltage is needed for a 25 watt light bulb for 30 seconds?
It depends in which country you are located. Through out the world that are different electrical voltages. The electrical manufactures knowing this and wanting to sell world wide make bulb to run on that countries electrical system. The two main voltages that bulbs operate on are; in 60 Hertz countries 120 volts and 50 Hertz countries 230 volts.
How much volts does a small light bulb need to be powered?
110 volts is what comes out of an average wall socket in America. A 100-watt bulb would be powered by 110 volts. You need to be more specific in your question to get a good answer. Small can't be measured.
How much amperage a 194 series bulb draws?
The 194 bulb is ~3.8 watts, at 14 volts they draw 0.271 amps.
How much heat does a light bulb make?
The electrical term Watts is a measure of heat. It is calculated by multiplying amps times volts, but it is still a measure of heat. A 50w light bulb made for 12 volts produces about the same amount of heat as a 50w light bulb made for 120 volts.
How much do an ordinary light bulb cost?
about 2.00 dollars. it depends on the size and shape and the number of volts you get!

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.
What is the time duration of a 9 volts battery using 5 volts bulb?
The light-bulb will probably burn out if you connect it directly. Other than that, you CAN'T calculate the time duration based on the data provided. The duration depends on how much energy the light-bulb uses, and how much energy the batter is able to store. Voltage is NOT a unit of energy.
What equation would you use to calculate how much current in AMPs is required to achieve the full 100 to output from a volt bulb?
The bulb is marked with the power (watts) and the voltage. Divide the watts by the volts and you have the amps.
Why does electrical bulb used at home does not glow when connected to a dry cell?
The key is your description of it as "bulb used at home". From that description, it's understood to be a bulb designed to be installed in a socket in the bedroom, closet, basement, etc., and powered by the mains voltage ... roughly 120 volts or 240 volts, depending on what country it's used in. The voltage between the terminals of the "dry cell" is about 1.5 volts. The power dissipated by any passive device is proportional to the square of the voltage across its ends. In the US or Canada, the power dissipated by the bulb would be (1.5/120)2 = 0.00016 of the power it's designed to use when glowing normally. In many European or Asian countries, the power delivered to the bulb is (1.5/240)2 = 0.000039 of the power it's designed to use when glowing normally. The filament in the bulb is not dissipating enough power to even get warm, and certainly much too little power to "incandesce" or 'glow'. In short, the voltage of the dry cell is only about 1.5 volts. That's the reason why dry cells are seldom used to operate air conditioners and refrigerators, or to start cars.
How much current would flow through a 75 w bulb in a 220 v curcuit?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
A 100-w light bulb is turned on it has an operating voltage of 120 V how much current flows through the bulb?
The formula you are looking for is I = W/E. Amps = Watts/Volts.
Why cant you touch a halogen bulb?
Because if you touch it, you may get dirt or oils from your skin on the bulb. Since halogen bulbs operate at a much higher temperature than conventional bulbs, the contaminants may cause the bulb to break. If you do touch the bulb, clean it with an alcohol swab before installing it.
