Question

A carbon resistor is coloured with four different bands red, green,orange and silver respectively.Find range of its probable resistance​

Answer 1

Answer:

25k$\pm$10% ohm

Explanation:

first two colours explains digits so based on

BLACK BROWN RED ORANGE YELLO GREEN BLUE VIOLET GREY WHITE accordingly  digits are

0 1 2 3 4 5 6 7 8 9

based on red, green two digits are 25

third colour tells number of zeros which is orange = 3 zoros=000

4th colour tells tolrence generaly silver which is 10%

resistave is 25000+10 %

=25k$\pm$10% ohm
