A carbon film resistor has colour code Green Black Violet Gold. The value of the resistor is
Options
- A( 50 M )
- B( 500 M )
- C( 500 5 % M )
- D( 500 10 % M )
Correct answer
C. ( 500 5 % M )
Step-by-step solution
Given, colour code on resistor is Green -5 ; Black -0 ; Violet -7 ; Gold -5 % First and second band corresponds to digit, third band corresponds to multiplier and fourth band corresponds to tolerance. Therefore, the value of resistor i 50 10⁷ 5 % =500 10⁶ 5 % =500 5 % M
