To calculate the percentage uncertainty of a quantity, you divide the absolute uncertainty by the measured value and multiply by 100.
In this case, the measured value is 3.2A and the absolute uncertainty is 0.2A.
So, the percentage uncertainty can be calculated as:
(0.2A / 3.2A) x 100 = 0.0625 x 100 = 6.25%
Therefore, the percentage uncertainty of I = 3.2A +/- 0.2A is 6.25%.
In this case, the measured value is 3.2A and the absolute uncertainty is 0.2A.
So, the percentage uncertainty can be calculated as:
(0.2A / 3.2A) x 100 = 0.0625 x 100 = 6.25%
Therefore, the percentage uncertainty of I = 3.2A +/- 0.2A is 6.25%.
