Hey there. Okay so im new to electronics and am having a problem... I need to turn on a transistor when a certain variable resistor is at 50k ohms. By my understanding this would require me to make a potential divider with R1 = 300k ohms and R2 = variable resistor (50k) since I am running the circuit from a 5V power supply and my transistor's threshold is at 0.7 ohms. The only reason I can think of for why it's not working is that my 300k resistance means there's not enough current left to turn on the transistor... Is there another way to do this? Or should i just look for a transistor that takes a super low current?
