Series Voltage Dividers

1. The current is similar in all of resistances in a series circuit.
2. Also, the voltage drop is equivalent to the product IR.
3. Hence, IR voltages are proportional to series resistances.
4. A higher resistance contain a greater IR voltage than a lower resistance in similar series circuit; equivalent resistances have the similar amount of IR drop across each of resistance.
5. If R₁ is double of R₂ then V₁ will be double of V₂. 
6. The series string might be considered like a voltage divider.
7. Each of resistance gives an IR drop V equivalent to its proportional part of the applied voltage. Described by formula,

                                                            V=R/R_T x V_T
