Problem

Two readings for a conductor at constant temperature are given: Point P: Current

= 0.25\,\text{A}

, Voltage

= 2.5\,\text{V}

Point Q: Current

= 0.75\,\text{A}

, Voltage

= 7.5\,\text{V}

a) Taking Voltage (

V

) on the vertical axis and Current (

I

) on the horizontal axis, calculate the slope of the line joining P and Q. b) If the axes are interchanged (Current on the vertical axis and Voltage on the horizontal axis), calculate the slope of the line joining the same two points. c) Show that the product of the two slopes is numerically equal to unity (use appropriate significant figures). a. a) Calculate the slope with

V

on vertical axis and

I

on horizontal axis. b. b) Calculate the slope with axes interchanged. c. c) Show that the product of the two slopes equals unity.
