What has to happen for the bulb to light up?
To light up, the bulb needs an electrical current flowing through it. This current is typically provided by connecting the bulb to a power source, such as a battery or outlet. Once the current flows through the bulb's filament, it heats up and produces light.
How much current flows in a 75-walt's light-bulb connected to a 110 voltage wall outlet?
The current flowing through the 75-watt light bulb connected to a 110-volt wall outlet can be calculated by using the formula: Power = Voltage x Current. Therefore, the current flowing through the light bulb would be approximately 0.68 amps.
The light bulb in your lamp has burned out so you replace it with a light bulb with 130 ohms that is plugged into a 100-V outlet what is the current flowing through the bulb?
0.8A

Current = (voltage) / (resistance) = 100/130 = 0.769 A = 769 milliamperes (rounded)
Can a 9V battery power a 120V light bulb?
im not sure if this will work or not but... If you use a 9v battery threw an inverter, then a step-up transformer to convert 9v DC to 120v ac i think it will light the bulb, however current decreases when you do that and i dont know how much a light bulb needs..worth a try, i might actually try it now
Can a light bulb work on a DC voltage?
It can, but if you're wanting to run a 120v light bulb on DC, you'll need 120v DC to get the rated output. That's a lot of batteries. It's easier, and more sensible, to find a DC rated light bulb, such as an RV bulb.
How do you wire 240V to 120V?
What specifically are you wiring? A light bulb would operate dim, a motor will burn up. The current increases thereby requiring larger wire and current protection.
If you put a 60W 120V bulb in a 120V lamp that has a transformer for 240V and plug it into a 240V outlet will it work or blow the circuitry?
Off hand no but your explanations are not clear as to who is doing what to whom,,
What is the difference between a 120v bulb and a 110v?
There is no practical difference between a 120V bulb and a 110V bulb. Both are designed to work with the standard voltage in most household electrical systems, which is 120V in the US. The slight variation in voltage is within the acceptable tolerance range for most light bulbs.
How many amps does 65 watt light bulb draw?
A 65-watt light bulb operating at 120 volts draws approximately 0.54 amps of current. You can calculate this by dividing the wattage (65 watts) by the voltage (120 volts) to get the amperage.
What size resistor do you need to power a 14 volt bulb from a 120 outlet?
To power a 14 volt bulb from a 120 volt outlet, you can use a resistor with a value of around 820 ohms to limit the current and avoid damaging the bulb. This calculation is based on Ohm's Law (V=IR), where V is the voltage drop across the resistor (120V - 14V), and I is the current flowing through the circuit.
