Current through one LED in series with 2.2 Ω:

Above 20 mA: too much for a common 5 mm LED.

2.2 Ω is a standard value in the E6, E12, E24 series, so it comes in almost every resistor kit.

Same first two colors, different multiplier:

What are the colors of a 2.2 Ω resistor?

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

What is the SMD code for 2.2 Ω?

2R2 on 3-digit resistors and 2R20 on 4-digit (1%) resistors.

How much current flows through a 2.2 Ω resistor at 5 V?

2.27 A, dissipating 11.4 W: more than a standard resistor can handle.

Which resistors get mixed up with 2.2 Ω?

red, red, silver, gold is 220 mΩ and red, red, black, gold is 22 Ω: only the third band changes, so check it carefully.
