As suggested by ACuriousMind in this comment and by Kyle Kanos in this comment the recommended site for asking your question may very well be Physics.SE. If you use the tag ohms-law, the tag will automatically be converted to tag:electrical-resistance which has 2646 questions so far.
There's also 514 questions with the "ohms-law" tag at Electrical Engineering SE. They actually have a tag for ohms-law that won't get converted into a more general tag like electrical-resistance.
The Engineering.SE also has a few tags related to electronics.
If you ask the question on one of the sites (e.g. Physics.SE) and it turns out to be more appropriate for a different site (e.g. if it's very engineering-related and much more likely to get an answer at ElectricalEngineering.SE), questions can be migrated between the sites as long as the migrations happens within 60 days of the question first being posted. There is actually a close reason on Physics.SE that is described as follows:
"This question appears to be about engineering, which is the application of scientific knowledge to construct a solution to solve a specific problem. As such, it is off topic for this site, which deals with the science, whether theoretical or experimental, of how the natural world works."
You probably have enough site suggestions now, but I'll briefly mention another site that might be of interest, which is Matter Modeling SE since the policy there is essentially that if someone wants to answer the question, then it's on-topic. A question will almost always only be considered for closure if it can't be answered by anyone for a while (e.g. "needs details for clarity") or if it's a VLQ (very low quality in the typing/formatting) or if it's a duplicate of an existing question.
