The Colour coding on a carbon resistor is shown in the given figure. The resistance value of the given resistor is :
A
(5700 $$\pm$$ 285) $$\Omega$$
B
(7500 $$\pm$$ 750) $$\Omega$$
C
(5700 $$\pm$$ 375) $$\Omega$$
D
(7500 $$\pm$$ 375) $$\Omega$$
Explanation
R = 75 $$\times$$ 102 $$\pm$$ 5% of 7500
R = (7500 $$\pm$$ 375) $$\Omega$$
