200 V @ 10 mA R, 150 V @ 1 mA RL3 R, 100 V @ 1 mA Vs = 200 V %3D RL2 RL1 Rg IB 3 mA
determine the values for the divider resistors R1 R2 and R3
The equivalent circuit, with assumed current in each element is shown below:
From the circuit, the current in resistor 3 is equal to the current IB which 3 mA, one terminal of resistor 3 is connected to ground and the second terminal of resistor 3 is connected to the point where the voltage is 100 V.
For resistor 2, one terminal is connected to the point where the voltage is 100 V and the second terminal of resistor 3 is connected to the point where the voltage is 150 V.
For resistor 1, one terminal is connected to the point where the voltage is 150 V and the second terminal of resistor 3 is connected to the point where the voltage is 200 V.
To calculate the current in resistor 2, apply KCL at node where the voltage is 100 V:
To calculate the current in resistor 1, apply KCL at node where the voltage is 150 V:
