The current in the resistor if the color code is red, orange, orange, silver why?

resistance = 23* (10)^3 (+ or -)10 = 23010 or 22990
current = ( voltage / resistance)= (50 / 23010)= 2.2 mA
current = ( voltage / resistance)= (50 / 23010)= 2.2 mA

I'm not satisfy with priyaaru ans. because 23*(10)^3(+or-)10% means 23000(+or-)10% means 23000(+or-)2300.

Colour code is like BBROYGBVGW
We used say as: BB Roy Great Britain Very Good Wife
Black 0 1 1
Brown 1 1 1 10
Red 2 2 2 100
Orange 3 3 3 1,000
Yellow 4 4 4 10,000
Green 5 5 5 100,000
Blue 6 6 6 1,000,000
Violet 7 7 10,000,000
Gray 8 8 100,000,000
White 9 9 1,000,000,000
None 20%
Silver 10%
Gold 5%
SO RED is 2 orange 3 and third orange 10 to the power of that vlaue so 10000
so R=23000
I=V/R
=50/23000
=2.2mA
