Question

Show that the data in the last column of Table 2-2 are correct.

Short answer

The data given in the table 2-2 is correct.

Step-by-step solution

Given information

The following table is given

Calculations

The expression for error is given by:

$E=-\frac{R}{R_c+R}\times 100\%$

here, R is the standard resistance, and R_cis the circuit resistance.

$$\begin{gathered} \left(i\right)Row1 \\ E=-\frac{1}{1+1}\times 100\%=-\frac{1}{2}\times 100\% \\ E=-50\% \\ \left(ii\right)Row2 \\ E=-\frac{1}{10+1}\times 100\%=-\frac{1}{11}\times 100 \\ E=-9.1\% \\ \left(iii\right)Row3 \\ E=-\frac{1}{100+1}\times 100\% \\ E=-0.99\% \\ \left(iv\right)Row4 \\ E=-\frac{1}{1000+1}\times 100\% \\ E=-0.1\% \end{gathered}$$
