The difference between the indicated value and true value of a quantity is known as :
Answer: B
The difference between the indicated and true value is the absolute error.
\[ \delta A = A_{m} - A_{t} \]
where \(A_{m}\) is the measured (indicated) value and \(A_{t}\) the true value. The relative error is this difference divided by the true value, \(\delta A/A_{t}\), often expressed as a percentage.
Gross errors are human blunders, such as misreading a scale or recording the wrong figure. Dynamic error is the difference between the true and indicated value of a quantity that is changing with time, caused by the instrument's slow response, rather than the general definition asked for here.
