Two bulbs having power of 50 W and 25 W respectively are connected with the same source. Which has higher resistance? What is their ratio?

Explanation

To solve the problem, we need to determine the resistance of each bulb based on their power ratings and then compare them to find which one has a higher resistance and the ratio of their resistances.

### Step-by-Step Solution:

1. **Understanding the relationship between Power and Resistance**:
The power \( P \) of an electrical device is given by the formula:
\[
P = \frac{V^2}{R}
