I experimented again with lighting a fire using batteries and chewing gum paper.
I did this experiment in 2010.
This time, I measured the current using a DC clamp meter from GVDA.
The maximum current flows 6.3A.

![12V car bulb connect to 220V directly
This is series capacitor current limit circuit. Widely used in transformerless power supply.
However, it is dangerous because of the high potential difference with the ground.
In this kind of circuit, may damage the bulb by over current flows due to harmonics. (Current : 2 × π × f × C × V [A] ) 12V car bulb connect to 220V directly](https://i.ytimg.com/vi/4HI3JEzjyu8/mqdefault.jpg)
