Two bulbs are rated 60 W, 220 V' and '60 W, 110 V respectively. Calculate the ratio of their resistances.

Explanation

To solve the problem of finding the ratio of the resistances of two bulbs rated at 60 W, 220 V and 60 W, 110 V respectively, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the relationship between power, voltage, and resistance**:
The power (P) consumed by a resistor (or bulb) can be expressed in terms of voltage (V) and resistance (R) using the formula:
\[
P = \frac{V^2}{R}
