In the colour coding system of carbon resistors, the tolerance (in %) shown by gold band is____.

Explanation

To determine the tolerance percentage shown by the gold band in the color coding system of carbon resistors, follow these steps:

### Step-by-Step Solution:

1. **Understand the Color Coding System**:
- The color coding system is used to identify the resistance value and tolerance of resistors. Each color corresponds to a specific digit or tolerance value.

2. **Identify the Colors**:
- The colors used in the coding system include:
- Black, Brown, Red, Orange, Yellow, Green, Blue, Violet, Grey, White, Gold, Silver, and None.
- The first ten colors represent digits (0-9), while Gold and Silver represent tolerance values.

3. **Determine the Tolerance Values**:
- The tolerance values associated with the gold and silver bands are:
- Gold: 5%
- Silver: 10%
- No band: 20%

4. **Conclude the Tolerance for Gold**:
- Since the question specifically asks for the tolerance shown by the gold band, we can conclude that the tolerance is **5%**.

### Final Answer:
The tolerance (in %) shown by the gold band is **5%**.
