Q.No.13.3: - What are the resistances of the resistors given in the figure A and B? What is the tolerance of each? Explain what is meant by tolerance?

Q.No.13.3: - What are the resistances of the resistors given in the figure A and B? What is the tolerance of each? Explain what is meant by tolerance?

(Sorry for Diagram but I’m trying to describe this figure here)

1^st band is Brown 2^nd is Green 3^rd is Red 4^th is Gold. In B fig. 1^st band is Yellow 2^nd is White 3^rd is Orange and 4^th is Silver.

Ans: - For Figure A

First band brown   =        1

            Second band Green =     5

             Third band Red (have number two so)= 00

             Now,       R   =   1500Ω

             Fourth band Gold which shows tolerance = ±5%

So,                       R   =   1500Ω±5%

For Figure B

                    First Band Yellow  =        4

                    Second band White=        9

                    Third band orange =        000 (no. of zeros)

                              R     =     49000 Ω

                    Fourth band silver =        ±10%

Now resistance is

                              R     =     49000±10% Ω

Tolerance: -

       Tolerance means the possible variation from the marked value.
