We have a `30 W, 6 V` bulb , which we want to glow by a supply of `120 V` . What can be done for this ?

Explanation

To solve the problem of glowing a `30 W, 6 V` bulb using a `120 V` supply, we need to follow these steps:

### Step 1: Calculate the Resistance of the Bulb
The power (P) and voltage (V) of the bulb are given. We can use the formula for power to find the resistance (R) of the bulb.

\[ P = \frac{V^2}{R} \]
