Frequently asked questions
What are the colors of a 2 kΩ resistor?
On a 4-band resistor: red, black, red, gold. On a 5-band resistor: red, black, black, brown, brown.
What is the SMD code for 2 kΩ?
202 on 3-digit resistors and 2001 on 4-digit (1%) resistors.
How much current flows through a 2 kΩ resistor at 5 V?
2.5 mA, dissipating 12.5 mW. A 1/8 W resistor is enough.
Which resistors get mixed up with 2 kΩ?
red, black, brown, gold is 200 Ω and red, black, orange, gold is 20 kΩ: only the third band changes, so check it carefully.
