Colour Coding of Resistors

Q. A carbon resistor of $(47\pm 4.7)k\Omega$ is to be marked with rings of different colours for its identification. The colour code sequence will be

1. 
   Yellow-Green-Violet-Gold
2. 
   Violet-Yellow-Orange-Silver
3. 
   Green-Orange-Violet-Gold
4. 
   Yellow-Violet-Orange-Silver

Q. What is the reason for partial differentiation in the proof of propagation of errors in parallel combination of resistors

Q. For a colour coded carbon resistance, initial three bands are red and fourth band is silver. Its resistance is

1. $222\Omega \pm 10\%$
2. $2200\Omega \pm 10\%$
3. $333\Omega \pm 5\%$
4. $33000\Omega \pm 10\%$

Q. What is the resistance of a carbon resistance which has bands of colours brown, black and brown

1. $100\Omega$
2. $1000\Omega$
3. $10\Omega$
4. $1\Omega$

Q. I have a resistor marked with colours Red, Blue, Yellow and Gold from left to right. What is its resistance?

1. $23k\Omega \pm 5\%$
2. $260k\Omega \pm 5\%$
3. $620k\Omega \pm 10\%$
4. $32k\Omega \pm 5\%$
