Voltage divider

 

1) With two resistors in series, the sum of the voltage drop across each equals the total voltage drop across both.

2) To determine the voltage between the two resistors, we use the voltage divider formula.

3) The voltage divider formula says Vout = Vin* (R2/(R1+R2))

4) This turns out to be very useful
