SECTION 7Analog Switches for Digital Circuits
IS THERE REALLY GOLD at the end of a rainbow? That’s only wishing for power. But the knowledge of how to use voltage dividers? THAT is POWER! There is real power in this knowledge! Knowing this gives you the power to control. Electronics is about control.
Lesson 23 Understanding Voltage Dividers
While playing with a potentiometer and one fixed resistor, we can adjust the pot’s resistance to give us any voltage at the midpoint. We can use this flexibility to our advantage, but first, we have to understand what’s happening so we can control it.
You know that voltage is used as it passes through resistor loads. The higher the value of the resistor, the greater the amount of voltage used. You already ...
