What is the formula for calculating zero error??? |
| Answer» There is no formula dear for that please query ur doubts below by reading this-:Can you explain the calculation of zero error with an example?Zero error arises when the measuring instrument does not start from exactly zero (When at rest).Due to this zero error is present in each reading of the measure.There are two types of zero error : positive zero error and Negative zero error.(Taking Vernier caliper as an example)Positive zero error :If the zero marking of the Vernier scale lies on the right hand side of the zero marking of the main scale , then the error is said to be positive zero error. Look at the position of zero of the vernier scale on main scale.For example : if the reading is 0.1 mm then it is said that the caliper has an error of +0.1. To eliminate positive zero error the zero error should be subtracted from the total reading. For example if the total reading is 3.56 cm and the error is +0.05 then the actual reading would be 3.51 cm.THANK YOU @diti. | |
