    Did Nikola Tesla use much math in his work?

    Most of his work is pretty straight-forward and can be explain easily with words but did he have any contribution with mathematics or use any advance maths in his work?

    Can I use a multimeter on a multimeter?

    So I have two cheap multi-meters and I've been going around the house and my parents car testing it on voltage. One multimeter I can take out the circuti board, I can see the fuse, and resistors and the conductive path lines. So what I am wondering is if I can use my second multimeter (they are...

    What does Open Circuit Voltage mean?

    I have a multimeter and for the "ohmeter section" for resistance it goes from a range of ~ 200 Ohms to 2000 kilo-ohms and then says also... Max. Open Circuit Voltage: about 3V Overvoltage protection: 250V AC Thank you in advance

    What are ways in which a multimeter can "break"?

    The digital multimeter I have says "Overload protection: F 250mA/250V Fused (10A range unfused) Max. Input Current: 10A (For inputs >2A: measurement duration<10 secs, interval > 15 minutes)" It also says in the manual that the 10A jack is not fused...

    How many volts can a multimeter read?

    I have only tested mine (it is a cheap one $20) it on a 9V battery, what is the limit? My multimeter starts from 1000V DC then 200,20, 2000m,200m... I am a noob with this so sorry if I don't make sense

    Did Nikola Tesla discover a way to harness free energy?

    That is why I am asking because there are a lot of unsourced articles say that he has... did you read

    Did Nikola Tesla discover a way to harness free energy?

    And did he have patent/s for it... I understand that their are a lot of hoaxes and unsourced information out there so I want to know if there is some truth to the claim. I understand that energy can not be created or destroyed but what free energy is referring to is energy that is released...
