The Purpose of Choke in Tube Light is to Increase the Voltage Momentarily
Choke, also known as an inductor, is an essential component in a tube light. It is used to regulate the current flow and voltage in the circuit. The purpose of the choke in a tube light is to increase the voltage momentarily. Let's understand this in detail.
Why is Voltage Important in a Tube Light?
A tube light works on the principle of gas discharge. When an electric current is applied to a gas-filled tube, it produces ultraviolet light. The ultraviolet light then reacts with the phosphor coating on the inside of the tube, producing visible light.
To initiate the gas discharge, a high voltage is required. The voltage required to start the gas discharge is known as the striking voltage. Once the gas discharge is initiated, the voltage required to sustain it is lower than the striking voltage.
The Role of Choke in Tube Light
The choke in a tube light is connected in series with the tube. It is designed to offer high resistance to the flow of current when the voltage is low. This high resistance limits the current flow, preventing the tube from drawing excessive current.
When the switch is turned on, the voltage across the tube light is low. The choke offers high resistance, limiting the current flow. This causes the voltage to build up across the tube.
Once the voltage across the tube reaches the striking voltage, the gas discharge is initiated. The voltage required to sustain the gas discharge is lower than the striking voltage. At this point, the choke offers low resistance, allowing the current to flow smoothly through the tube.
Conclusion
In summary, the purpose of the choke in a tube light is to increase the voltage momentarily. This is achieved by limiting the current flow when the voltage is low, causing the voltage to build up across the tube until the striking voltage is reached. Once the gas discharge is initiated, the choke offers low resistance, allowing the current to flow smoothly through the tube.
