A carbon film resistor has colour code Green Black Violet Gold. The value of the resistor is

A)  \[500\pm 5%\text{ }M\Omega \]

B)  \[50M\Omega \]

C)  \[-500\pm 10%M\Omega \]

D)  \[500M\Omega \]

Correct Answer: A

Solution :

 :          The number assigned to green, black and violet are 5, 0 and 7. For gold, tolerance is 5%. \[\therefore \]Resistance value of the given resistor is \[R=50\times {{10}^{7}}\Omega \pm 5%=500M\Omega \pm 5%\]
