How is you know if a mineral passes the fluorescence test?
The fluorescence is experimentally identified.You need an ultraviolet lamp to irradiate the mineral sample.
How do you change operating voltage of metal halide lamp from 240 to 120?
The lamp needs to be rated for the voltage applied to it. The fixture in which the lamp is installed also needs to be rated for the voltage. So, it is not a matter of changing the lamp, it is a matter of having the fixture and lamp that are properly rated for the voltage that you are applying to it.
What voltage mercury lamp works?
the supply voltage to a mercury vapour lamp (from the electromagnetic ballast) is 130vac
How does changing voltage across a lamp affect the power consumption of the lamp?
because it does!
Fluorescent lamp low pressure mercury vapour?
A fluorescent lamp refers to a low pressure mercury-vapor gas-discharge lamp that uses fluorescence in order to produce visible light. It is also called a fluorescent tube.
In a circuit of two lamps in parallel if there is a voltage of 6 V across one lamp what is the voltage across the other lamp?
6 Volts.
What happen to lamp if over voltage?
A lamp will only operate at its rated power if it is subjected to its rated voltage. Increase that voltage will increase the power of the lamp -in other words, it will operate more brightly. This is how 'photoflood' lamps operate -they are deliberately designed to operate at overvoltage. Of course, this reduces the life of the lamp.
Why do the voltage drops of an inductor and a lamp in a series ac circuit not equal the applied voltage?
The voltage is greater than the applied voltage, why?
Why a lamp cannot run with the telephone line voltage?
A lamp can be run by power from a telephone line.
Why does a 25 watt bulb glow brighter than 60 watt in a series circuit?
Because the filament of a 25-W lamp has a higher resistance than that of a 60-W lamp and, therefore, will experience a greater voltage drop -the lamp with the voltage drop closer to its rated voltage (in this case, the 25-W lamp) will be the brighter.
What is function of the choke in lamp circuit?
The function of a choke in a lamp circuit is to produce high voltage. In tubelights, the high voltage is essential for ionisation of the gas which is present in tubelights.
Could you use a short wire with gold to power a light bulb?
In order to 'power' a lamp, you need to connect that lamp to a voltage supply. But why would you use gold wire when copper is a better conductor?
