What is voltage divider rule?

       The voltage across a single resistance or a combination of resistance in a series  circuit can be determine with out 1st finding the current is the voltage divider rule is applied 

   DIAGRAM:-

According to the ohm's law 

                                 V= IR 

                                 I=V/R  

       Total resistance Rt= R¹+R²

       =V¹= IR¹ =V/R¹=V/R¹.R² *R¹

       =V²= IR² =V/R²=V/R¹.R² *R²

  NOTE:-  

        V¹=VR¹/R¹R²

        V²= VR²/R¹R²

 Hence 

       The voltage divider rule said that a voltage across a resistance in a series circuit is equal to the value of the resistance time's the total voltage across the series resistance divided by the total resistance of the circuit.
