Question

While performing the experiment of ohm's law,a student has plotted the graph given along side . Find resistance of the conductor.
a. 1 ohm
b.100 ohm
c.3 ohm
d 10 ohm
Graph :
V=0.3, 0.6, 0.9
I =30, 60, 90

Answer 1

Answer:

Please give the graph too.

Explanation:

Answer 2

Answer: (d) 10 ohm

Explanation:

we know that 1 Amphere = 1000 milliamphere

therefore, 30 milliamphere in ampere = 30/1000= 0.03

now, R= V/I

R= 0.3×100/0.03×10=10 ohm
