Determine the resistance of the carbon resistor in the figure given be

1.	Determine the resistance of the carbon resistor in the figure given below
Answer» The answers for a and b are as follows : a) $22 \times 10^2 \pm 10 %$ % b) $47 \times 10^1 \pm <klux>5</klux> %$ % Explanation : RESISTER colour coding uses coloured bonds to quickly identify a resistor's resistance value ad its PERCENTAGE of tolerance with the physical size of the resistor indicating its voltage rating . The first two colours signify digits . The 3rd colour SIGNIFIES multiplier . The 4th colour tells about the tolerance of the resistor . The resistor colour CODES are always read starting from the let to the right. The larger width tolerance band oriented to the right side indicates tolerance . So, for part a : Tolerance for silver = 10 % and multiplier for red = 2 Hence , resistance = $22 \times 10^2 \pm 10 %$ % And also for part b : Tolerance for gold = 5 % and multiplier for brown = 1 Hence , resistance = $47 \times 10^1 \pm 5 %$ %

Determine the resistance of the carbon resistor in the figure given below

Answer»

a) $22 \times 10^2 \pm 10 %$ %

b) $47 \times 10^1 \pm <klux>5</klux> %$ %

Explanation :

RESISTER colour coding uses coloured bonds to quickly identify a resistor's resistance value ad its PERCENTAGE of tolerance with the physical size of the resistor indicating its voltage rating .
The first two colours signify digits .
The 3rd colour SIGNIFIES multiplier .
The 4th colour tells about the tolerance of the resistor .

The resistor colour CODES are always read starting from the let to the right.
The larger width tolerance band oriented to the right side indicates tolerance .

So, for part a :

Tolerance for silver = 10 % and multiplier for red = 2

Hence , resistance = $22 \times 10^2 \pm 10 %$ %

And also for part b :

Tolerance for gold = 5 % and multiplier for brown = 1

Hence , resistance = $47 \times 10^1 \pm 5 %$ %
