Hi guys,

So I've been wondering, if I were to do Kelvin's thunderstorm\water dropper experiment and present it in front of people, what things can I actually measure (for example, something as a function of the other or the dependency between two things)? Or in other words, what calculations and measurements can I actually write down and check with my system?Thank you and happy holidays.
 
Physics news on Phys.org
anyone?
 
Some obvious things come to mind:
- volts produced
- net average current and power
- time to produce a given charge
- net efficiency of converting potential energy of the water into electrical power
