The final expression will be A*B, and press Calculate: Calculate the total charge value when a current of 0.15 ± 0.01 A passes through the circuit for 120 ± 1 s:
So if this is a case, never use A + A, but rather 2*A and never A*A*A but rather A^3!Īngles for trigonometric functions can be provided in degrees or radians, and that should be reflected by setting a yellow button to “DEG” or “RAD”.īear in mind the importance of units in any of calculations!ġ.The charge passing through an electrical circuit is defined by: Q = I * t, where I is the current and t is the time. The application deals with independent, random errors. The evaluated expression may consists of a functions, that provided by row of the appropriate buttons and any numerical value.Ĭomponents and functions can be added directly to expression field by pressing the corresponding buttons. The application allows input of value-error pairs that used as a parameters in the final expression.Įrror values should be provided in absolute (100 +/- 5) or in a relative (per cent) format (100 +/- 5%).
The application is available on Apple iOS Store. Uncertainty Calculator is a application that aims to evaluate the error propagation throughout the mathematical expressions comprised of variables of uncertain values.
