Let's solve the resistor color code problem step by step.
We are given 6 resistors, each with colored bands. We need to determine the
first digit,
second digit, and
multiplier for each based on the color codes provided in the table.
Color Code Reference Table:
| Color | 1st & 2nd Digit | Multiplier (3rd Band) |
|---------|------------------|------------------------|
| Black | 0 | 1 |
| Brown | 1 | 10 |
| Red | 2 | 100 |
| Orange | 3 | 1K |
| Yellow | 4 | 10K |
| Green | 5 | 100K |
| Blue | 6 | 1M |
| Violet | 7 | 10M |
| Gray | 8 | 100M |
| White | 9 | 1000M |
| Gold | - | 0.1 |
| Silver | - | 0.01 |
Now let’s analyze each resistor from top to bottom:
---
Resistor 1:
Bands:
Orange, White, Orange
- 1st Digit: Orange → 3
- 2nd Digit: White → 9
- Multiplier: Orange → 1K
✔ So:
3, 9, 1K
---
Resistor 2:
Bands:
Brown, Black, Violet, Yellow
Note: This has
four bands, so the first three are significant digits and multiplier, and the fourth is tolerance (not needed here). But since we only have columns for 1st digit, 2nd digit, and multiplier, we assume the first three bands matter.
So:
- 1st Digit: Brown → 1
- 2nd Digit: Black → 0
- Multiplier: Violet → 10M
✔ So:
1, 0, 10M
---
Resistor 3:
Bands:
Red, Green, Brown
- 1st Digit: Red → 2
- 2nd Digit: Green → 5
- Multiplier: Brown → 10
✔ So:
2, 5, 10
---
Resistor 4:
Bands:
Brown, Black, Brown
- 1st Digit: Brown → 1
- 2nd Digit: Black → 0
- Multiplier: Brown → 10
✔ So:
1, 0, 10
---
Resistor 5:
Bands:
Red, Red, Red
- 1st Digit: Red → 2
- 2nd Digit: Red → 2
- Multiplier: Red → 100
✔ So:
2, 2, 100
---
Resistor 6:
Bands:
Brown, Orange, Violet, Yellow
Again, four bands — use first three:
- 1st Digit: Brown → 1
- 2nd Digit: Orange → 3
- Multiplier: Violet → 10M
✔ So:
1, 3, 10M
---
Final Answer Table:
| Resistor | 1st Digit | 2nd Digit | Multiplier |
|---------|-----------|-----------|------------|
| 1 | 3 | 9 | 1K |
| 2 | 1 | 0 | 10M |
| 3 | 2 | 5 | 10 |
| 4 | 1 | 0 | 10 |
| 5 | 2 | 2 | 100 |
| 6 | 1 | 3 | 10M |
---
Summary of Values:
1.
39 × 1K = 39,000 Ω = 39 kΩ
2.
10 × 10M = 100,000,000 Ω = 100 MΩ
3.
25 × 10 = 250 Ω
4.
10 × 10 = 100 Ω
5.
22 × 100 = 2,200 Ω = 2.2 kΩ
6.
13 × 10M = 130,000,000 Ω = 130 MΩ
> Note: The worksheet asks only for the
digits and multiplier, not the full value, so we fill in the table as shown above.
✔ Final Answer (to be filled in the boxes):
```
Row 1: 3, 9, 1K
Row 2: 1, 0, 10M
Row 3: 2, 5, 10
Row 4: 1, 0, 10
Row 5: 2, 2, 100
Row 6: 1, 3, 10M
```
