Answer:
B. 380 ± 10 Ω
Explanation:
The resistance can be calculated using the following equation
R = V/I
Where V = 2.00 ± 0.02 V and I = 5.3 ± 0.1 mA
First, we need to convert 5.3 ± 0.1 mA to A, so
5.3 ± 0.1 mA x 1 A/1000 mA = 0.0053 ± 0.0001 A
Then, we can calculate the resistance as
R = 2.0/0.0053 = 377.35 Ω
Now, we can calculate the uncertainity using the following equation:
[tex](\frac{\Delta V}{V}+\frac{\Delta I}{I})R=(\frac{0.02}{2.00}+\frac{0.1}{5.3})377.35=10.96\text{ }\Omega[/tex]
Therefore, the approximate answer is
B. 380 ± 10 Ω
