प्रतिरोध = 484 Ω

Explanation:

Given,

शक्ति

, P = 100 वाट

वोल्टेज ,V = 220 volt

प्रतिरोध ,R = ?

We know that,

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

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

R = \frac{220\times 220}{100}

R = \frac{48400}{100}

R = 484 Ω

प्रतिरोध = 484 Ω

The resistance of the bulb is 484 Ω

Explanation:

It has been given that

Power = 100 W

V = 220 V

R = ?

The relation between power and voltage is given by

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

Substituting the known values

100=\frac{220^2}{R}\\\\100=\frac{48400}{R}\\\\100R=48400

Now, divide both sides by 100

R=\frac{48400}{100}\\\\R=484\ohm

Therefore, the resistance of the bulb is 484 Ω
