What does a condenser do in a fluorescent light?

The ballast controls the current flowing through the valve, and the condenser makes the ballast more efficient.

What does a lighting capacitor do?

When one places a capacitor in a circuit containing a light bulb and a battery, the capacitor will initially charge up, and as this charging up is happening, there will be a nonzero current in the circuit, so the light bulb will light up.

What is the role of condenser and choke used in fluorescent lamp?

The purpose of the choke, which is basically a coil of wire, is to provide a very high voltage initially between the filaments (across the two ends of the tube light). Once the gas in the tube is ionized, which is normally Mercury vapour, the choke then provides a low voltage. Its in two combinations starter and choke.

Which function of choke is in fluorescent tube?

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 difference between a capacitor and a condenser?

Capacitors are passive electronic elements with the ability to store electrical charges. A condenser refers to a device that can transform a substance from its vapor state to a fluid state.

How does a a condenser work?

A condenser usually consists of one or possibly more lenses and a variable-aperture diaphragm. Light passes through the diaphragm, onto the specimen focused by the lens or lenses. After light moves through the sample, it deviates into the cone of light we spoke about earlier and onto the objective lens.

What is the function of the condenser in a microscope?

The function of the condenser The condenser fulfills two functions in the microscope. It provides an area of evenly-illuminated light in the field of view at the specimen plane and illuminates the aperture of the objective uniformly with light of sufficient yet controllable angle.

What is the function of capacitor in a tube light?

A tube light consists of a filament & a choke or inductor for the lightening purpose. So, when supply is given to it, we can see a delay in its switching action. This is due to the choke. An inductor doesnt allows sudden change in its current; so after some time it glows. So, a capacitor is connected in parallel with thius circuit.

How does a condenser microphone work?

The condenser microphone is a transducer, just like any other microphone, meaning it transforms one type of energy into another. In this case it turns mechanic energy into electric energy; air sound wave into audio signal.
