Question

1. The graph of current I ( on y-axis ) vs. potntial difference V ( on x- axis ) is found to be a straight line. The slope of the straight line gives :

a. potential difference

b. resistance

c. reciprocal of resistance

d. current

Answer 1

$$\begin{gathered} Slope=\frac{I}{V}=\frac{1}{R} \\ henceitgivesreciprocaloftheresis\tan ce. \end{gathered}$$
