Divider circuits: a) voltage divider and b) current divider.
Consider the voltage divider shown in figure 1.3a.
The voltage across the input source is 
and the voltage across the output between terminals A and B is
.
The output voltage from the voltage divider in thus
Example: Determine an expression for the voltageon the voltage divider in figure 1.4.
Figure 1.4: Example voltage divider.
We take the bottom line in figure 1.4 to be at ground and define the current flowing between
Applying Kirchoff's voltage law for the input source gives
Combining the above two results and solving for
