Hello, everyone i'm new in electronics so i wanted to know when every time we use a resistor where it to place on the negative side or positive because i saw in many videos someone use on the negative and someone on the positive but which way the right way to use it negative side or positive side ?
Second thing if i know the supply voltage and i have potentiometer , led etc.. how can i find out what type of resistor i need 100ohm, 200ohm etc.. if someone can explain me thsnks very much
