I am confused about the switching of this circuit. I can control the V1 input line. Output line is R4 load line. My Vbase (V1) is 0V, and Vbe is 0V. Transistor is off and collector should see 0V. That is the graph which I added. But, the 5V still supplies voltage and current to the R4 load.
How can i make this switching circuit? In this even if its off I see 5V on R4 and current.
Some other scenarios I tried: remove R3 100ohm. In that case there is 5V and 5mA on R4 which makes sense. Another case: remove R4 and have R3. In that case I see 5V across Q1 and no current. But there is still a potential difference that my device input will be able to read correct (despite no current)?
