The circuit of a voltage divider may be drawn with the two resistors vertical, not horizontal. If there are two resistors in series across a voltage source, then the circuit is a voltage divider.

There are variations on this circuit that use diodes instead of a resistor to achieve the required voltage drop. If the divider is not suitable for your application and you still eschew a ...

and read the resulting voltage off of a voltage divider with an ADC. But that means using the voltage divider equation, and the difference in voltage between keys can get very small. Dropping the ...

First find the total resistance of the voltage divider. If the thermistor is moved to a freezer its resistance rises to \(40k\Omega\). The resistance of the resistor remains the same. We can ...
