# AS Physics - Percentage Uncertainty help Watch

1. The maximum voltage V was measured using a moving coil meter marked in mm divisions, a deflection of 25 mm representing a potential difference of 0.01 V
The distance d between the centres of the coils was measured using a metre rule.

(a) (i) Determine the percentage uncertainties in V and d for the third set of data.
The third set of data is

Meter deflection/mm = 32 V/v = 0.0128 d/m = 0.152
2. bump
3. do you know how to calculate percentage uncertainties?
4. (Original post by nao123)
do you know how to calculate percentage uncertainties?
yes
absolute uncertainty / value * 100
I have some answers but I just want to check that they're correct
5. Do you know which paper this is from?
