If a light bulb is connected between 2 wires and both wires have 300 volts of electrical energy is the light bulb lit?
A light bulb connected between to wires, each having 300 volts to ground that are in phase, will not light, because there is no differential voltage available to do any work. If each wire has 300 volts to ground and are out of phase (600 volts between them) the light bulb will be lit, if it is rated at least for 600 volts, otherwise it will burn out.
How much current flows through a 60 watt bulb connected to 120 volts?
Using the Electrical Power Law, which is:The current (measured in amps) equals the power (measured in watts) divided by the potential difference (measured in volts)So a light bulb designed to use 60 watts of power when supplied with 120 volts must draw 60 watts divided by 120 volts, which is a current of 0.5 amps.The same answer could be expressed in a few different ways:500 milliwatts500 mW"1/2 an amp" !
A circuit has 25 ohm light bulb and t 120 volts what is the current?
I = E/R = 120/25 = 4.8 amperes
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.
When a light bulb is rated 100 w for 220 v supply. what is the resistance of the bulb and the peak voltage of the sources?
Ohm's Law: Resistance is voltage divided by current Power Law: Power is current times voltage Combining them gives: Resistance is voltage squared divided by power 220 volts squared divided by 100 watts = 484 ohms. Note that this is hot resistance. If you measure the bulb in the cold state, you will get an entirely different, smaller, value, due to the extreme temperature coefficient of the filament. Independently of that, since you ask for peak voltage, that means you are talking about an AC voltage source. We have to assume a sinusoidal waveform, and that the 220 volts was the RMS value. In this case, the peak value is simply the RMS value multiplied by the square root of 2, i.e. 0.707..., making the peak value 311 volts.
How many volts in a 60 Watt light bulb?
If a light bulb is rated at 60 Watts, the voltage will depend on the specific type of bulb. For a typical incandescent bulb, the voltage would be around 120 volts. However, for an LED or CFL bulb, the voltage could be different, such as 120 volts or 240 volts.
What does volts mean on a light bulb?
Electricity in your house or anywhere else comes in volts. When you screw in a light bulb, you screw it in to an electrical socket that has a certain number of volts. The socket can have 3 volts like a flash light, 12 volts like a car, 120 volts like American houses, or 240 volts like some Latin American houses. The light bulb is designed to work with one of those voltages. If you put a 240 volt bulb in a 120 volt socket, it will glow extremely dim. If you put a 120 volt light bulb in a 240 volt socket, it will glow extremely bright, but it will burn out in a short period of time. So you should put a 120 volt bulb in a 120 volt socket. In the United States, you will not have that trouble. However, if you take your yacht to a foreign country, you might put your light bulb in the wrong socket.Another AnswerA lamp will only operate at its rated power when subject to its rated voltage. So, if you want your lamp to operate at its rated power, you must connect it to a supply which provides its rated voltage

Will four extra volts make a small light bulb explode?
it all depends on what the bulb is rated for4 extra volts on a 120 volt bulb is negligable4 extra volts on a 1 volt bulb will definitely pop the element, but I don't think it would explodeAnswerDepends on the bulb voltage, but it shouldn't explode. If it's a 6volt bulb or lower, it would burn out quickly.If it's a 12volt bulb or higher, it may have a shorter life, but it would be brighter.
Why are there 14.5 volt automotive bulbs?
When the alternator on a vehicle is in the charging mode its output is close to 14.5 volts. If a bulb is rated at 12 volts, which is the voltage of a vehicle battery at rest, when the alternator comes on line at a higher voltage the life span of the bulb will be shortened.
WILL 103 VOLTS LIGHT A 60 WATT LIGHT BULB?
Yes, a 103 volt source will light a 60 watt light bulb. The relationship of the bulb's wattage output at a lower voltage, as to the normal voltage that the bulb is rated to operate on, the light output will be lower.
How many volts are in anonion to power a light bulb?
Onions don't have volts.
Can you use a 130 volt light bulb on a 120 volt supply?
Yes, in fact that is what a rough service bulb is rated at. The bulb used on a 120 volt system will have a reduced wattage output as to what it would be on 130 volts.
What does it mean by writing V and W in a bulb?
V on a light bulb means volts. W means watts.
How do you get amperes of 25 watts bulb?
To calculate the amperage of a 25-watt bulb, you need to divide the wattage by the voltage at which the bulb operates. For example, if the bulb operates at 120 volts, you would divide 25 watts by 120 volts to get the amperage.
When using a 9 volt battery on a closed circuit with 2 light bulbs how many volts are used to light each bulb?
Each light bulb will receive the full 9 volts from the battery in a series circuit, so each bulb will be operating on 9 volts.
What kind of light bulb will be lit by 5 volts?
Um, a 5 volt light bulb?
