Where is the impedance of a pure resistance plotted on rectangular coordinates?
On the vertical axis
On a line through the origin, slanted at 45 degrees
On a horizontal line, offset vertically above the horizontal axis
On the horizontal axis✓Correct answer
Explanation
On an impedance plot the horizontal axis carries the resistive component and the vertical axis the reactive component. A pure resistance has zero reactance, so it plots on the horizontal axis.
