Question

Why should we use fluorescent tubes in place of filament bulbs?

Answer 1

Filament bulbs:

1. In the case of filament bulbs, most of the power consumed by the filament having high resistance is emitted as heat, and only a small portion of electric power is emitted as light. So the filament bulbs are inefficient.
2. Their running cost is high because they consume more current.
3. In comparison to fluorescent tubes, they do not give much light and also their life is short.

Fluorescent tubes:

1. On the other hand, fluorescent tubes offer less resistance. Due to this, most of the power consumed by these tubes is emitted as light and only a small portion is emitted as heat. So these are highly efficient. Fluorescent tubes are almost three times as efficient as filament bulbs.
2. Their running cost is very less compared to the filament bulbs.
3. In comparison to filament bulbs, they give more light and have a long life.
4. This is why we should use fluorescent tubes in place of filament bulbs.
