Voltage x Current = Power

So Power / voltage = current

Now you do the math

How can you calculate the current in 40 X 40W tube lights in 230V?

power is = V2/R so 40x40= (230)2/R R= 33.25 now V= IR where I is current 230= IXR I= 230/33.25 = 6.9 amp


How discharge tube is different from tube light?

A discharge tube is a type of gas-filled tube that emits light when an electric current passes through it, commonly used in neon signs or plasma displays. On the other hand, a tube light is a type of fluorescent lamp that uses a phosphor coating inside a glass tube to produce light. While both types of tubes rely on gas and electric current to produce light, they differ in their construction and application.


What is ballast in tube light?

Ballast is a device used in fluorescent lighting fixtures to regulate the electric current flowing through the light tube. It helps to stabilize the electrical current and control the voltage to ensure the proper operation of the light, including starting and maintaining its brightness. Without a ballast, the tube light would not function correctly.


How tube light start by using starter?

A starter initially provides a path to complete the circuit. The tube light starts when the current flows through the ionized gas in the main tube. woodenboatusa.com


What is the function of a tube light ballast in a lighting fixture?

The function of a tube light ballast in a lighting fixture is to regulate the electrical current flowing through the fluorescent tube, providing the necessary voltage to start and maintain the light output.


How does electron allow a fluroscent tube to glow?

The electrons in the mercury arc current in the tube causes the mercury vapor to emit ultraviolet light. The inside surface of the tube is coated with a phosphor that glows with visible light when hit by ultraviolet light.


Why tube light glow in white colour?

Tube lights glow in white color because they contain a phosphor coating on the inside of the tube that emits white light when excited by electricity. The phosphor coating helps to convert the ultraviolet light produced by the electrical current into visible white light, resulting in the tube light emitting white light.


Which gas is found in tube light?

Tube lights contain a small amount of mercury vapor gas, which is used to produce ultraviolet light when an electric current passes through it. This ultraviolet light then causes the phosphor coating inside the tube to fluoresce and emit visible light.

How does tubelight glows?

A tubelight glows when an electrical current passes through mercury vapor inside the tube, causing it to emit ultraviolet light. This UV light interacts with the phosphor coating on the inside of the tube, producing visible light.


What is the difference between the normal light globe and a fluorescent tube?

"Normal" light globes use a glowing filament, heated by the current. Flourescent tubes ignite a gas within a tube, using an arc.
