Question

2) In ohm's experiment, the values of the unknown resistances were found to be 6.12,
6.22, 6.09, 6.15 ohm's. Calculate the absolute error, relative error and percentage
error in these measurements.​

Answer 1

Given

• The correct value of resistance = 6.12

• Experiment outcomes are 6.22, 6.09, 6.15

To Find

• Absolute Error

• Relative Error
• Percentage Error

Solution

Absolute Error = Actual value - Experimental Outcome

=> Required Absolute Errors are -> 0.10, 0.03, and 0.07 respectively.

Relative Error = Absolute Error/Actual Value

=> Required Relative Errors are -> 0.016, 0.005, and 0.011 respectively.

Percentage Error = Relative Error x 100

=> Required Percentage Errors are -> 1.6%, 0.5%, and 0.11% respectively.
