Question

a carbon resistere har Brown, black, red
and silver colour coding then find its value​

Answer 1

Answer:

According to the colour code, brown colour stands for 1, black for 0 and red for 2.

First and second band represents the first and second significant number respectively.

So, it is 10Ω.

Third band represents power of 10 by which it is raised, so it is 10

1

.

Last band represents the tolerance of resistor, so it is 2%.

Thus value of resistance, R=(10×10
