3900 means by color coding is
orange=3
white=9
red=100
orange=3
white=9
red=100

3.9k=3900
=>3 9 * 10^2
3-orange
9-white
2-red
=>3 9 * 10^2
3-orange
9-white
2-red

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

Orange, white, red, gold.
= 3 9 10^2 5%.
= 39*100 5%.
= 3900 5%.
= 3.9k 5%.
= 3 9 10^2 5%.
= 39*100 5%.
= 3900 5%.
= 3.9k 5%.

@M.V. Krishna is right.
Value of resistor is = 1st colour*2nd colour*10 to the power of 3rd colour.
Value of resistor is = 1st colour*2nd colour*10 to the power of 3rd colour.
