Question

4. The following table shows current in
Amperes and potential difference in
Volts.
a. Find the average resistance.
b. What will be the nature of the graph
between the current and potential
difference? (Do not draw a graph.)
c. Which law will the graph prove?
Explain the law.

V (Volts)
4
5
6

I (Amp)
9
11.25
13.5​

Answer 1

Answer:

a) average resistance

R(av)= (4/9 +5/11.25 + 6/13.25 )/3

= (0.444 +0.444 +0.444)/3

= 0.444 ohm

b) straight line_ because the ratio of voltage and current is same or constant)

c) ohms law.

hope it helps.
