Hi folks.
One of frequently asked interview question is-
Q. Why the symbol chosen for resistance is a zigzag line?
Answer- If same question were asked for inductor, you can answer it by inductor is basically a coiled conductor or for capacitor, It is two conducting plates separated by a dielectric- so we show plates.
Well, in network theory, we show straight line for a conductor with zero resistance. It basically indicates that current faces no problem for passing through it. To show the extra efforts put by current (that appear in the form of voltage drop), why not to increase the distance traveled by the current inside a resistor? So the resistor has a symbol where it indicates the opposition to the flow of current (as its basic definition says).
Thank you for your time. Please feel free to comment about your views and doubts.
