Presentation Transcript

  1. Sharing voltage

  2. Potential dividers Potential dividers reduce voltage. Varying the ratio of a pair of resistors changes the output voltage of a circuit. VIN R1 R2 VOUT = × VOUT VIN R1 + R2 R2 0V 0V VOUT will be a fraction of VIN. The magnitude of VOUT is dependent upon the ratio of the two resistors R1 and R2.

  3. Using the potential divider equation

  4. Sensors and potential dividers

  5. Potential divider questions

  6. Potential dividers summary
