Previous Year Question
According to the duality theorem, what is the dual of a series connection of resistors?
Correct answer: C
Explanation
In network duality, resistance R is paired with conductance G, series connection is paired with parallel connection, and voltage with current. Therefore the dual of series resistances is parallel conductances.
Step-by-step solution
Correct Answer
C — Parallel connection of conductances
Explanation
In network duality, resistance R is paired with conductance G, series connection is paired with parallel connection, and voltage with current. Therefore the dual of series resistances is parallel conductances.
