Question

7.(ii) in the graph shown, the resistance of the conductor will be
1
90
I (MA)
60+
30+
0.3
0.6 0.9
V (volt) +
(a) 1000 22
(b) 100
(c) 100
(d) 10​

Answer 1

Answer:

10 ohm

Explanation:

Here, R= resistance of the conductor.

From graph,

when V=0.3V, I=30mA = 30 × 10 ^-³ A

R= V/I = 0.3 / 30×10^-³ = 300 / 30= 10 ohm
