MULTIPLELOAD VOLTAGE DIVIDERS A multipleload voltage divider is shown in figure 365. An important point that was not emphasized before is that when using the 10% ruleofthumb to calculate the bleeder current, you must take 10% of the total load current.

Given the information shown in figure 365, you can calculate the values for the resistors needed in the voltagedivider circuits. The same steps will be followed as in the previous voltage divider problem.
Given:
The bleeder current should be 10% of the total load current.
Solution:
Since the voltage across R_{1} (E_{R1}) is equal to the voltage requirement for load 1, Ohm's law can be used to calculate the value for R_{1}.
Solution:
The current through R_{2} (I_{R2}) is equal to the current through R_{1}plus the current through load 1.
Solution:
The voltage across R_{2} (E_{R2}) is equal to the difference between the voltage requirements of load 1 and load 2.
Ohm's law can now be used to solve for the value of R_{2}.
Solution:
The current through R_{3} (I_{R3}) is equal to the current through R_{2} plus the current through load 2.
The voltage across R_{3} (E_{R3}) equals the difference between the voltage requirement of load 3 and load 2.
Ohm's law can now be used to solve for the value of R_{ 3}.
Solution:
The current through R_{4} (I_{R4}) is equal to the current through R_{3} plus the current through load 3. I_{R4} is equal to total circuit current (I_{ T}).
The voltage across R_{4} (E_{R4}) equals the difference between the source voltage and the voltage requirement of load 3.
Ohm's law can now be used to solve for the value of R_{ 4}.
Solution:
With the calculations just explained, the values of the resistors used in the voltage divider are as follows:
