| Apr 3, 2021 at 5:44 | comment | added | tobalt | Pay attention not to fry the 10 Ohm resistor when using a fresh battery. | |

SI units named after a person have their symbols capitalised but are lowercase when spelt out. See https://physics.nist.gov/cuu/pdf/sp811.pdf section 9.3 regarding kilohm.

Added image inline (cropped and resized for increased readability), to make it easier for readers to view it, instead of everyone needing to click an external link..
