4.3.4. Resistor Divider Voltage Reference

Try these first

1. 1.

   What is a resistor divider?

   Hint

   Think about how voltage is shared in a circuit.

2. 2.

   List one advantage of using a resistor divider.

   Hint

   Consider the materials involved.

3. 3.

   What is the main purpose of a resistor divider?

   • To amplify voltage
   • To divide voltage
   • To measure voltage

   Hint

   Think about how voltage interacts with resistors.

4. 4.

   True or False: Resistor dividers provide high accuracy in voltage references.

   • True
   • False

   Hint

   Remember the limitations discussed.

5. 5.

   Design a resistor divider with a total resistance of 10kΩ that gives a 4V output from a 12V supply. What are the resistor values?

   Hint

   Think about the total resistance and voltage ratio.

6. 6.

   How would you adjust a resistor divider if the output voltage is too low during testing?

   Hint

   Consider how changing resistor values affects the voltage division.
