This question already has an answer here:
So I bought an Arduino today, my high school grades were terrible but I decided to dive into electronic engineering anyway.
I am a total noob so please forgive me. So Ohm's law states v = R * I, therefore V/R=I. If I have 3.3 V output from an Arduino that shall give me 0.1 amp. and 10 ohm resistor will produce a current of 0.33 amp.
"Any electrical device used on a house wiring circuit can, under certain conditions, transmit a fatal current. While any amount of current over 10 milliamps (0.01 amp) is capable of producing painful to severe shock, currents between 100 and 200 mA (0.1 to 0.2 amp) are lethal."
Why am I still alive?
Scenario: I connected a 33 ohm resistor to 3.3 V Arduino output, according to a plan that shall produce 0.1 amp, but my multimeter reads 0.01 amps.
Again please forgive me, it is my first day of electronic engineering.
