Please explain your answer.

Answer 1

Table 1: 200 ohm resistor
Voltage	Current
V	mA	A
0	0	0
2	10.5	0.0105
4	21.2	0.0212
6	31.1	0.0311
8	41	0.041
10	51.1	0.0511
11	56.3	0.0563

The slope from the equation of the curve tells us the experimental resistance.

Experimental resistance from Table 1: 196.3 ohms

Table 2: 100 ohm resistor
Voltage	Current
V	mA	A
0	0	0
1	10.2	0.0102
2	21.1	0.0211
3	30.5	0.0305
4	41.8	0.0418
5	52.1	0.0521
5.5	58.4	0.0584

The slope from the equation of the curve tells us the experimental resistance.

Experimental resistance from Table 2: 94.81 ohms

We can see that both these curves are straight lines.Hence V=IR relation is satisfied and both these resistors satisfy Ohm's Law.

Nominal Value	Resistance determined from slope of graph. Measured value
200 ohm resistor	196.3 ohm	1.85%
100 ohm resistor	94.81 ohm	5.19%
