@Raman.

Gold 5%, Silver 10% tolerance.

@Koppaka Rajesh.

How would you know it is 5%?

@M.V. Krishna is right.

Value of resistor is = 1st colour*2nd colour*10 to the power of 3rd colour.

Orange, white, red, gold.

= 3 9 10^2 5%.
= 39*100 5%.
= 3900 5%.
= 3.9k 5%.

By rule of colour coding of resistor, 3 is orange, 9 is white And 2 is red so Calculate colour code 392 first two are as it is And last digit take power of 10.

i.e 10^2 = 100 then 39*100 = 3900 = 3.9k gold is tolerance 10.
