Chapter 3, Problem P 3.3-5(choose chapter or problem)
The model of a cable and load resistor connected to a source is shown in Figure P 3.3-5. Determine the appropriate cable resistance R so that the output voltage \(v_o\) remains between 9 V and 13 V when the source voltage \(v_s\) varies between 20 V and 28 V. The cable resistance can assume integer values only in the range 20 < R < 100 \(Omega\).

QUESTION:
The model of a cable and load resistor connected to a source is shown in Figure P 3.3-5. Determine the appropriate cable resistance R so that the output voltage \(v_o\) remains between 9 V and 13 V when the source voltage \(v_s\) varies between 20 V and 28 V. The cable resistance can assume integer values only in the range 20 < R < 100 \(Omega\).
ANSWER:
Step 1 of 3
Applying voltage division gives ,
