Current through one LED in series with 820 Ω:

820 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 820 Ω resistor?

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

What is the SMD code for 820 Ω?

821 on 3-digit resistors and 8200 on 4-digit (1%) resistors.

How much current flows through a 820 Ω resistor at 5 V?

6.1 mA, dissipating 30.5 mW. A 1/8 W resistor is enough.

Which resistors get mixed up with 820 Ω?

grey, red, black, gold is 82 Ω and grey, red, red, gold is 8.2 kΩ: only the third band changes, so check it carefully.
