Question
In the circuit shown, the Norton equivalent resistance (in ) across terminals a-b is _______.
Correct answer
1.3 to 1.35
Solution
To find the Norton equivalent resistance across terminals a-b, we apply a test voltage at terminals a-b and find the current entering terminal 'a'.
Let and (ground).
The current through the resistor is:The dependent voltage source has a value of .
Applying KCL at node 'a':The equivalent resistance is:The range specified is 1.30 to 1.35.
