Find the resistance of 60 W, 240 V bulb.

Answer

To find the resistance of a 60 W, 240 V bulb, we can use the relationship between power (P), voltage (V), and resistance (R). The formula we will use is:

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

### Step-by-Step Solution:

1. **Identify the given values:**
- Power (P) = 60 W
- Voltage (V) = 240 V

2. **Rearrange the formula to find resistance (R):**
- From the formula \( P = \frac{V^2}{R} \), we can rearrange it to solve for R:
\[ R = \frac{V^2}{P} \]

3. **Substitute the known values into the formula:**
- Substitute V = 240 V and P = 60 W into the rearranged formula:
\[ R = \frac{240^2}{60} \]

4. **Calculate \( 240^2 \):**
- Calculate \( 240^2 \):
\[ 240^2 = 57600 \]

5. **Divide by the power (P):**
- Now, divide \( 57600 \) by \( 60 \):
\[ R = \frac{57600}{60} = 960 \, \Omega \]

6. **Final Result:**
- The resistance of the 60 W, 240 V bulb is \( 960 \, \Omega \).
