Problem
For a certain resistor the following measurements were recorded:
(
V
,
I
)
=
(
1.0
V
,
0.20
A
)
,
(
2.0
V
,
0.41
A
)
,
(
3.0
V
,
0.59
A
)
(V, I) = (1.0\,\text{V},\,0.20\,\text{A}),\ (2.0\,\text{V},\,0.41\,\text{A}),\ (3.0\,\text{V},\,0.59\,\text{A})
(
V
,
I
)
=
(
1.0
V
,
0.20
A
)
,
(
2.0
V
,
0.41
A
)
,
(
3.0
V
,
0.59
A
)
. Assuming the resistor follows Ohm’s law, the best estimate of its resistance is a)
