What kind of gas is inside tv picture tube?
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).
Was the first amplifying tube a triode?
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.
What is the proper bias current for an EL34 tube with 265V on the plate in push-pull topology class AB operation?
38
Are Fluorescent and LED lights the same thing?
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.
What unit measures tube current?
Measure the plate resistors' (R) voltage (E) and use Ohms law to convert that to amps (I). I=E/R
How do you calculate the current in 40W tube light in 230V?
Voltage x Current = Power So Power / voltage = current Now you do the math
What is the function of choke in tube lights?
To limit the current flowing through the fluorescent tube once its gas has ionised.
Lights that glow when an electric current causes ultraviolet waves to strike a coating inside a tube are called?
fluorescent lights
What are the benefits of using t8 LED tube lights compared to traditional fluorescent tube lights?
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.
What are the benefits of using T5 LED tube lights 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.
Why do tube lights do not get heated?
because tube lights are made of glasses. and when its break down then nobody gets heares
Is it possible to connect two tube lights with a single choke and also you need the circuit to connect the tube lights?
yes
What are the benefits of using a t8 LED tube light compared to traditional fluorescent tube lights?
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.
What are the benefits of using a t5 LED tube light compared to traditional fluorescent tube lights?
T5 LED tube lights are more energy-efficient, have a longer lifespan, produce less heat, and offer better brightness and color consistency compared to traditional fluorescent tubes. They also start instantly without flicker, contain no mercury, and require less maintenance.
What is the full-wave tube current when the filament current is 4.6A and the tube voltage is 70 kVp?
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.
What are the benefits of using LED fluorescent tube lights over traditional fluorescent tube lights?
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.
How do you calculate the cross sectional area of a rectangular tube?
To calculate the cross sectional area of a rectangular tube, multiply the widths of two adjacent sides of the tube.
