# Determine Resistance value of Resistors

Determine the nominal resistance values of these resistors, given their band colors, and also express the allowable tolerance in ohms (i.e. what the minimum and maximum acceptable resistance values are for each resistor given its advertised tolerance).

## Determine Resistance value of Resistors

For example, a 25 kΩ resistor with a 10% tolerance rating would have an allowable tolerance of +/- 2.5 kΩ.

1. Red, Org, Blu, Gld =

2. Brn, Blk, Grn, Sil =

3. Blu, Blk, Brn, Gld =

4. Yel, Vio, Red, Sil =

5. Grn, Brn, Yel =

6. Wht, Blu, Blk, Sil =

7. Gry, Grn, Org, Gld =

8. Org, Org, Gld =

9. Vio, Red, Sil, Gld =

10. Brn, Red, Blk, Sil =

### Solution:

• Red, Org, Blu, Gld = 23 MΩ, +/- 1.15 MΩ
• Brn, Blk, Grn, Sil = 1 MΩ, +/- 100 kΩ
• Blu, Blk, Brn, Gld = 600 Ω, +/- 30 Ω
• Yel, Vio, Red, Sil = 4.7 kΩ, +/- 470 Ω
• Grn, Brn, Yel = 510 kΩ, +/- 102 kΩ
• Wht, Blu, Blk, Sil = 96 Ω, +/- 9.6 Ω
• Gry, Grn, Org, Gld = 85 kΩ, +/- 4.25 kΩ
• Org, Org, Gld = 3.3 Ω, +/- 0.66 Ω
• Vio, Red, Sil, Gld = 0.72 Ω, +/- 0.036 Ω
• Brn, Red, Blk, Sil = 12 Ω, +/- 1.2 Ω
