What is percentage uncertainty I=3.2A+/-0.2A?
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%.
To find the percentage uncertainty for the current I = 3.2A +/- 0.2A, you can use the formula:
Percentage Uncertainty = (Uncertainty / Measurement) x 100
Given that the uncertainty is 0.2A and the measurement is 3.2A, you can substitute these values into the formula:
Percentage Uncertainty = (0.2A / 3.2A) x 100
Simplifying this expression:
Percentage Uncertainty = 0.0625 x 100
Percentage Uncertainty = 6.25%
Therefore, the percentage uncertainty in the current I = 3.2A +/- 0.2A is 6.25%.
