The colour code for a carbon resistor of resistance 0.2 k 10 % is
Options
- Ared, grey, brown, silver
- Bred, green, brown, silver
- Cred, grey, silver, silver
- Dred, black, brown, silver
Correct answer
D. red, black, brown, silver
Step-by-step solution
Resistance of carbon resistor, aligned R &=0.2 k 10 % &=200 10 % &=20 10¹ 10 % aligned According to the colour code for carbon resistor, the colour assigned to number 2,0 and 1 are red, black and brown. For colour used for tolerance of 10 % is silver. Colour code are red, black, brown and silver.
