Vedclass · Answer

(B) According to the standard carbon resistor color code:$1$. The first color (violet) represents the first significant digit: $7$.$2$. The second color (yellow) represents the second significant digit: $4$.$3$. The third color (brown) represents the multiplier: $10^1$.$4$. The fourth color (golden) represents the tolerance: $\pm 5\%$.Calculating the resistance value:$R = (74 	imes 10^1) \pm 5\% \,\Omega$$R = 740 \pm 5\% \,\Omega$Since $740 \,\Omega$ is the nominal value,the closest option provided is $741 \,\Omega$.
