Current through one LED in series with 12 kΩ:

12 kΩ is a standard value in the E12, E24 series, so it comes in almost every resistor kit.

Same first two colors, different multiplier:

What are the colors of a 12 kΩ resistor?

On a 4-band resistor: brown, red, orange, gold. On a 5-band resistor: brown, red, black, red, brown.

What is the SMD code for 12 kΩ?

123 on 3-digit resistors and 1202 on 4-digit (1%) resistors.

How much current flows through a 12 kΩ resistor at 5 V?

417 µA, dissipating 2.08 mW. A 1/8 W resistor is enough.

Which resistors get mixed up with 12 kΩ?

brown, red, red, gold is 1.2 kΩ and brown, red, yellow, gold is 120 kΩ: only the third band changes, so check it carefully.
