Resistor Color Code
Mediumphysics
Color bands Brown-Black-Red indicate resistance? (Third band μltiplier)
Select the correct option:
Solution
Incorrect! Answer:
1 kΩ
- Color Code Table (B B R O Y G B V G W):
- Brown = 1
- Black = 0
- Red = 2
- Decoding Process:
- 1st band (Brown): First digit = 1
- 2nd band (Black): Second digit = 0
- 3rd band (Red): Multiplier = 102=100
- Calculation:
- Value =(10)×100=1000 Ω
- Unit Conversion: 1000 Ω=1 kΩ.
