Due to voltage fluctuations, the temperature of an electric bulbs rises from 2000 K to 3000 K. Calculate the percentage rise in the electric power consumed.

Explanation

To calculate the percentage rise in the electric power consumed by the bulb when the temperature rises from 2000 K to 3000 K, we can follow these steps:

### Step 1: Understand the relationship between power and temperature
The power emitted by a black body is directly proportional to the fourth power of its temperature. This can be expressed mathematically as:
\[ P \propto T^4 \]

### Step 2: Define the initial and final temperatures
Let:
...
