I Why in an electric circuit with only a generator the resistance R=infinity?

AI Thread Summary
In an electric circuit with only a generator, the resistance is considered infinite because there is no completed circuit, resulting in zero current flow. While the actual resistance is not truly infinite, it is treated as such for educational simplicity. The discussion emphasizes the importance of having a complete circuit for current to flow effectively. Additionally, clarification on the term "generator" and a schematic diagram are suggested to enhance understanding. Overall, the concept revolves around the relationship between circuit completion and resistance.

Because you don't have a completed circuit. Just an open. Of course, in reality the resistance isn't infinite, just very, very high. But we call it infinite to simplify things when teaching things to students.

Also, there's no need to throw half a dozen question marks into a sentence. One will suffice.

Because the current is zero.

What's "a generator" in your question? Can you post a schematic?
 
As worded, the question implies to me zero resistance, not infinite. So yeah, we need a diagram.
 
I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
