Why a bulb is called 0 watt?

We all call a bulb as 0 watt bulb. But do you know why it is called 0 watt bulb? 

                       ---------   Zero watt bulb

Actually, no electrical equipment will do a work on 0 watt. To do work it will take electricity in either some points. 

Then why is it called 0 watt after all?

The reason for this is that the electrical meter we had till a few years ago was an analogue meter. And the analogue meter cannot read some watts.

 If that zero watt bulb is actually a 7 watt bulb, then people could not see anything rising on the meter. So this misconception had formed in the minds of the people that this is a 0 watt bulb.

And that's where this 0 watt bulb started. And this term became very popular in India.

Hope this helps you . Thank you ❤️.
