Practical Electronics/Voltage Divider

Intro A network of two resistors connected as shown Analysis Vo = I R2 Formula Choosing Value for R R2 R2 = 0 , Vo = 0 R2 >> R1 , Vo = Vi R1 R1 = 0 , Vo = Vi R1 >> R2 , Vo = 0 R1 = R2 Vo = ½ Vi When R1 = R2 , the output voltage is exactly halved of the input voltage Summary There is no gain for this network, since Vo never greater than Vi . This network can be used as Voltage Attenuator, Voltage Follower, Voltage Halved, or Voltage Ground When the value of R2 > R1, this network acts as Voltage Attenuator When the value of R2 = 0 or R1 >> R2, this network acts as Voltage Ground When the value of R1 = 0 or R1 << R2, this network acts as Voltage Follower When the value of R2 = R1 = R then this network acts as Voltage Halved
