  • Many enough, and how to make different values.

    posted by 1076901 on 03/07/2015


    I do not need them often, but now I have all the values I need. Some of you might like to know how to make other values. To make more resistance you just connect two or more in series. If you need a lower value or a value in between the standard, calculation for parallel connection is like this: (1/R1)+(1/R2)+( as many R's as you want)=1/R total. If you need 1/2W you can parallel connect two, but they must then be of double value to keep the wanted resistance. Example: You need 100K 1/2W, parallel connect two 220K, or if you want 3/4W use 3 x 330K. Hope this is useful for those of you that is not educated electro guys.

    With a collection like this you can make exactly the value you need, but most of the time you will find one that is close enough for normal use.

    Quality seems to be good, even with this very low price. One of the strips was much shorter, so it was easy to see there was only 391, but for this low price that is totally OK. I'm still smiling.
