A) I got 3 types of resistors a 10k,100k and 180k resistor since they're mixed up I have to figure out the resistance of them.. first I asked in irc in some electronics channels though people just wondered why these resistors look so strange .. no idea if they had an idea about resistors or not nevermind the links below helped me out.
