How tube light circuit is connected?
How tube light circuit is connected?
A wire already connects port 2 and pin 1 of the terminal 2. From another terminal of the switch the wire is carried out up to tube light set up and connected to port 1. One terminal of choke or ballast is connected to port 1 and another terminal is connected to pin 1 of terminal 1.
What is tube light choke?
The purpose of the choke is to provide a very high voltage initially between the filaments (across the two ends of the tube light). Again once the gas in the tube is ionized the choke provides a low voltage. A choke is a coil of wire. Fluorescent tubes/lamps are filled with mercury vapor.
Why choke is connected in the circuit of a fluorescent tube explain it?
The choke primarily serves to limit current flow to the correct level for the tube. It also can be used during startup to provide an inductive ‘kick’ forming a momentary higher-voltage pulse to start the lamp.
What is the function of electric choke?
In electronics, a choke is an inductor used to block higher-frequency alternating currents while passing direct current (DC) and lower-frequencies alternating current (AC) in an electrical circuit.
What is the use of electric choke?
A choke, also known as an inductor, is used to block higher-frequency while passing direct current (DC) and lower-frequencies of alternating current (AC) in an electrical circuit. The name comes from blocking, or “choking”, high frequencies while passing low frequencies.
How the tube light circuit is connected and how does it work?
Working Principle of Tube Light When the switch is ON, full voltage will come across the tube light through ballast and fluorescent lamp starter. Then gas inside the starter gets ionized due to this full voltage and heats the bimetallic strip that is caused to be bent to connect to the fixed contact.
How do I know if my tube light is working?
Using a multimeter will determine if the electrodes still hold conductivity. If the electrodes are not intact, the bulb will not have a current running through it. Place the probes on both pins of the tube light to get an accurate reading. If there is no reading on the multimeter, the bulbs should be replaced.
