The resistance `R = V//i`, where `V = 100 +- 5 V and I = 10+- 0.2 A`.

1.	The resistance `R = V//i`, where `V = 100 +- 5 V and I = 10+- 0.2 A`. What is the total error in `R`?
Answer» `R = (V)/(I) (( Delta R )/( R ) xx 100)_(max) = (Delta V)/(V) xx 100 + (Delta I)/(I) xx 100 ` ` = (5)/(100) xx 100 + (0.2)/(10) xx 100` `= ( 5+2)% = 7%`

Using the expression `2d sin theta = lambda`, one calculates the values of `d` by measuring the corresponding angles `theta` in the range `0 to [email protected]`. The wavelength `lambda` is exactly known and error in `theta` is constant for all values of `theta`. As `theta` increases from `[email protected]`A. the absolute error in `d` remains constant.B. the absolute error in `d` increases.C. the fractional error in `d` remain constant.D. the fractional error in `d` decreases.
