Pre Lab 6¶
Here are some help for Pre lab 6!
Part 1¶
This is a simple Uncertainties Calculations with Ohm Laws. Use the formula:
\[R = \frac{\Delta{V}}{I}\]
Use the rules of multiplications to finish the question.
Attention
Read the question carefully for which terms should be present!
Part 2¶
A circular cross-section should give you the sense of the formula for A:
\[A = \pi r^2\]
Now, obtain the formula in term of d (diameter) and the uncertainty for A.
Tip
Use the power rule for this task!
Next, we need to find uncertainty for the inverse of A:
\[x = A^{-1}\]
Hopefully, you see it is applied with the rules of multiplication.
