Answer:
193 or 1902
Step-by-step explanation:
Resistor values are coded using some number of significant digits, usually 2 or 3, followed by a power-of-ten exponent.
19×10³ would be encoded as 193
190×10² would be encoded as 1902

Additional comment
The values of resistors have been standardized for certain tolerances. The closest 1% or 0.5% resistors to this value are 19,100 ohms, encoded as 1912. The standard values are listed in the attached table.
A 19,000 ohm resistor would generally be a special-order part. The coding of its value would depend on what manufacturer it is ordered from.
