maybe it makes you give a pass to the law of ohm, the current that limits a resistance being of the same value, is the same, regardless of size, of course you have to put the closest in wats to the one you need, you can put the 1/2 wats always and when I have the space. Be sure to set the correct value, indicated in the diagram or on the resistance body if it is visible. comment if you know how to interpret that values .... greetings.
