Who can tell us how much energy the piezoelectric device in the lighter releases at a time? Thank you!
The piezoelectric device in the lighter has a high voltage, but a small current, so the energy released at one time is very small. It's hard to measure. It can be estimated indirectly:
Hand pressure: about 5 Newton, pressing stroke: about 0.008 m, hand work: 5*0.008=0.04 Joule, then the energy released by one discharge will not be greater than 0.04 Joule.
It is more scientific to estimate the energy released by discharge by measuring the work done by the compression spring.
