The temperature of the filament in a light bulb is about `1800^(@)C`, what will it be on Fahrenheit scale?

Answer

To convert the temperature of the filament in a light bulb from Celsius to Fahrenheit, we can use the following formula:

\[ F = \frac{9}{5}C + 32 \]

Where:
- \( F \) is the temperature in Fahrenheit,
- \( C \) is the temperature in Celsius.

### Step-by-Step Solution:

1. **Identify the given temperature in Celsius**:
- The temperature of the filament is given as \( C = 1800^\circ C \).

2. **Substitute the value of \( C \) into the formula**:
\[ F = \frac{9}{5} \times 1800 + 32 \]

3. **Calculate \( \frac{9}{5} \times 1800 \)**:
- First, calculate \( \frac{9}{5} \):
\[ \frac{9}{5} = 1.8 \]
- Now multiply by 1800:
\[ 1.8 \times 1800 = 3240 \]

4. **Add 32 to the result**:
\[ F = 3240 + 32 = 3272 \]

5. **Final result**:
- The temperature of the filament in Fahrenheit is:
\[ F = 3272^\circ F \]

### Conclusion:
The temperature of the filament in a light bulb, which is \( 1800^\circ C \), is equivalent to \( 3272^\circ F \).
