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
There are two main types of lights that are typically tube shaped:"neon lights" - these use mixtures of noble gases (e.g. helium, neon, argon, krypton, xenon) to produce different colors. These are usually used for advertising signs for businesses.fluorescent lights or UV lights - these use mercury vapor to produce UV light (in fluorescent lights a thin coating of a fluorescent powder transforms the UV light to visible light).
If by triode, you mean "a three-electrode tube", then yes. You need a source of current into the device, a control electrode, and an "outlet" for the controlled current. Although there were radically different types of construction, all early amplifying tubes were triodes of some kind.

NO. Fluorescent lights and LEDs are NOT the same thing, other than the fact that they both produce light. A fluorescent light consists of a glass tube or envelope with a powder [phosphor] coating on the inside of the glass which when "excited" by electrical energy created by current running through a gas, also inside the envelope, releases some of that energy in the form of light. An LED on the other hand is a solid state device with no tube, phosphors, or gas. It also converts electrical energy to light but by the interaction of two dissimilar electrically conductive compounds inside of a transparent or translucent plastic body.
Measure the plate resistors' (R) voltage (E) and use Ohms law to convert that to amps (I). I=E/R
Voltage x Current = Power So Power / voltage = current Now you do the math
To limit the current flowing through the fluorescent tube once its gas has ionised.

T8 LED tube lights are more energy-efficient, have a longer lifespan, produce better quality light, and are more environmentally friendly compared to traditional fluorescent tube lights.
T5 LED tube lights are more energy-efficient, have a longer lifespan, produce better quality light, and are more environmentally friendly compared to traditional fluorescent tube lights.
because tube lights are made of glasses. and when its break down then nobody gets heares
yes
T8 LED tube lights are more energy-efficient, have a longer lifespan, produce better quality light, and are more environmentally friendly compared to traditional fluorescent tube lights.
T5 LED tube lights are more energy-efficient, have a longer lifespan, produce better quality light, and are more environmentally friendly compared to traditional fluorescent tube lights.
The full-wave tube current can be calculated using the relationship between filament current, tube voltage, and the specific characteristics of the tube. However, without specific details about the tube's design and efficiency, it's difficult to provide a precise value for the full-wave tube current. Generally, the tube current can vary significantly based on the tube's construction and operational parameters, so additional context is necessary for an accurate calculation.
LED fluorescent tube lights have several advantages over traditional fluorescent tube lights. They are more energy-efficient, have a longer lifespan, produce less heat, and are more environmentally friendly due to their lower mercury content. Additionally, LED lights offer better color rendering and do not flicker like traditional fluorescent lights.
To calculate the cross sectional area of a rectangular tube, multiply the widths of two adjacent sides of the tube.
