Current through one LED in series with 82 Ω:

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

82 Ω 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 82 Ω resistor?

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

What is the SMD code for 82 Ω?

820 on 3-digit resistors and 82R0 on 4-digit (1%) resistors.

How much current flows through a 82 Ω resistor at 5 V?

61 mA, dissipating 305 mW. A 1 W resistor is enough.

Which resistors get mixed up with 82 Ω?

grey, red, gold, gold is 8.2 Ω and grey, red, brown, gold is 820 Ω: only the third band changes, so check it carefully.
