Question

how do i draw this graphb) graphc) using the graph, find the number of coils in the iron resistor at a resistance of 10 ohms

Answer 1

ANSWERS

(b) Graph:

(c) 25

Step-by-step explanation

(b) To graph the results, we have to graph each point. The x-coordinate is the number of coils and the y-coordinate is the resistance,

And then, since this is linear, we can join the points with a line.

(c) Now, we have to draw a horizontal line where the resistance is 10 Ω, and then a vertical line from where this line intersects the graph,

Hence, the number of coils for a resistance of 10 Ω is 25 coils.
