Three bulbs of 40 W , 60 W , 100 W are arranged in series with 220 volt supply which bulb has minimum resistance

Options

A. `100 W`
B. `4 W`
C. `60 W`
D. Equal in all bulb

Explanation

To determine which bulb has the minimum resistance among the three bulbs (40 W, 60 W, and 100 W) arranged in series with a 220 V supply, we can use the formula for resistance based on power:

### Step-by-Step Solution:

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