The voltage isn't decided by the lamp, but by the supply the lamp is hooked up to.
The formula for current is Amps = Watts/Volts. The lamp itself would draw 4.16 amps. Since the voltage of the lamp is 12 volts there is a internal transformer involved in the fixture itself. It doesn't matter what the input (primary) voltage to the transformer is, so long as it meets the manufacturer's specification as to the proper voltage to operate the fixture.
This type of conversion could be troublesome. To change to 120 volt system means that the feed wire has to be rated for underground use and rated at 300 volts. Where as the existing low voltage wiring does not have to be subjected to these rules due to using low voltage. The lamp socket in the post is next. It has to be rated at 120 volts and the existing low voltage socket can not be used.
Operating at half the required voltage, the lamp will not operate at full capacity if it comes on at all.
Ohm's Law: Resistance is voltage divided by current 110 volts divided by 0.4 amperes is 275 ohms.
Running a 277 volt lamp on 220 volts can potentially damage the lamp and pose safety risks. It is recommended to use the correct voltage to ensure the proper operation and safety of the lamp. If necessary, consult an electrician to reconfigure the electrical circuit to match the correct voltage for the lamp.
The projector needs a new lamp?
A flashing engine light is usually a misfire.
Because your lamp is probably in wrong.
The projection lamp, from the sound of things.
To determine the amps for a halogen lamp, divide the wattage of the lamp by the voltage it operates on. The formula is: Amps = Watts / Volts. This will give you the amperage required for the halogen lamp.
No, it is not recommended to use a 110-volt lamp in a country that operates on 220 volts without a voltage converter or transformer. The lamp could be damaged or pose a safety risk if plugged directly into a higher voltage outlet. It is advisable to purchase a lamp designed for 220 volts in European countries.
The operating voltage of a mercury lamp typically ranges from 100 to 300 volts, depending on the specific type and size of the lamp.
The resistance of a lamp operating at 115 volts and using 0.25 amp of current is 460. The relationship I used is Ohm's law.
110 volts was chosen to make light bulbs practical and economically competitive with gas lighting. Edison selected 100 volts as a compromise between distribution costs and lamp costs. Generation was maintained at 110 volts to allow for a voltage drop between generator and lamp.[1]
The voltage isn't decided by the lamp, but by the supply the lamp is hooked up to.
the potential at which neon bub just start glow is called flashing potential.and quenching potential is a potential at which neon bulb stop to conduct..
