Question

The sequence of bands marked on a carbon resistor are: Red, Red, Red, Silver. Write the
value of resistance with tolerance.​

Answer 1

Answer:

R=22×1000000+- 10% is the value of resistance

Answer 2

Concept:

We will use the table chart for this question.

Given:

The coloured rings marked on a carbon resistor are red, red, red and silver.  

Find:

the tolerance of the resistor.

Solution:

Tolerance is defined as the percentage of error in the resistance of the resistor.

• The first two bands indicate the value of the resistance.
• The third band, simply indicates the number of zeros. (multiplier)
• The fourth band indicates the tolerance.

Given colours :

From the table we have,

Red - 2, Red - 2, Red - 10² (Multiplier), Silver - 10% (Tolerance)

The resistance is 22 × 10² Ω ± 10%.

Hence the value of resistance with tolerance is 22 × 10² Ω ± 10%
