The tolerance level of a resistor with the colour code red, blue, orange, gold is

Options

A. `+- 5%`
B. `+- 10 %`
C. `+- 20 %`
D. `+- 40 %`

Answer

To determine the tolerance level of a resistor with the color code red, blue, orange, and gold, we can follow these steps:

### Step 1: Identify the Colors
The color code provided is:
- Red
- Blue
- Orange
- Gold

### Step 2: Determine the Tolerance Level
The tolerance level is indicated by the fourth color in the resistor color code. In this case, the fourth color is gold.

### Step 3: Recall Tolerance Values
The tolerance values associated with the colors are:
- Gold: ±5%
- Silver: ±10%
- No color: ±20%

Since the fourth color is gold, the tolerance level for this resistor is ±5%.

### Step 4: Conclusion
Thus, the tolerance level of the resistor with the color code red, blue, orange, and gold is **±5%**.

### Final Answer
The tolerance level is **±5%**.
