Hello all firdt time poster and im sure il be posting more
Going back to basics im re- teaching myself from my old gcse books from ten year ago lol.
I got the 4 band resistors down to a T but i recently bought a pack of leds that specified what resistors i weanted for them, i asked for 12 volt ones and what i got in the post with leds were blue resistors with 5 bands on them, so i looked up color codes for 5 bands and the diagrams all say that there should be 1 band on the lip of the resistor the other 4 in side the middle before the last lip..Well mine have 3 in middle and 1 on each lip so how do i tell which end to use? i tried to input into a calculator both ways for one sequence beinghbrown violet black black yellow but it dont look right? brown and yellow on the ends? one result was a 1 Mohm for an led seems high?
some clarification and help would be most apreciated.
Also Whats difrence between E12 and E3 series resistors 1/4wat 5% ?
they both have resistors in there series which are same in both? i dont get that. thanks in advance
