    Why use a voltage divider and not just a variable resistor?

    Thank you for your insights, it has given me something to study :) Thank you for your replies.

    Why use a voltage divider and not just a variable resistor?

    Ok, I think I am understanding. So, in my attachment, even though the circuit below is also viable, we only use the one with the voltage divider (the one above) because of the higher reliability and control? Or is the one below just not viable at all? (ignoring the values, I just sketched this...

    Why use a voltage divider and not just a variable resistor?

    I understand that, thank you. What if, however, the other end of the LDR is going into, say, an IC (ignoring the middle state), or the base of a transistor? This is more the focus of my question :) In the original circuit, I connected the components so that one terminal of the LDR was in Vcc...

    Why use a voltage divider and not just a variable resistor?

    Hello, everyone. I have a simple question I just can't get my head around. Some time ago I was working with an LDR for a circuit that would be based on light. Naturally, what I wanted was that the my LDR (connected directly to Vcc) gave me (on the other terminal) a signal that would be later...
