V=12.48 V correct to 2 decimal places V = 12.48 \text{ V correct to 2 decimal places} V=12.48 V correct to 2 decimal places I=3.12 A correct to 3 significant figures I = 3.12 \text{ A correct to 3 significant figures} I=3.12 A correct to 3 significant figures I=VR I = \frac{V}{R} I=RV​

III = current, VVV = voltage, RRR = resistance

By considering bounds, work out the value of R R\,R to a suitable degree of accuracy. Give a reason for your answer.
