Answer:
Explanation:
resistor follow colour code pattern for giving user information about its value like 10ohm ,20 ohm etc.
colour code are as follow
black 0 10^0
brown 1 10^1
red 2 10^2
orange 3 10^3
yellow 4 10^4
green 5 10^5
blue 6 10^6
voilet 7 10^7
grey 8 10^8
white 9 10^9
gold 0.1 5%
silver 0.01 10%
number like 1 2 3 are for first colour in a resistor
for example your question first number is 2 i.e for red one
the next is green i.e 5
the third represent the multiplier value i.e 10^0 or 10^1 etc
in your case its is voilet i.e 10^7 and the last colour is gold or silver will give you information about corection i.e in your case it is gold which acc to table has coreection of 5%
so finally you can find your resistor value i.e (25*10^7+5%)ohm or (25*10^7-5%) ohm
to rember trick for the table is as follow
