Question

. A bulb is rated at 220 V, 175 W. What is its resistance?​

Answer 1

Explanation:

V=IR

220=175×R

Resistance =220/175

=1.25(app)

Answer 2

Answer:

Here's your answer

From power formula

P=V^2/R

given is

V=220V and P= 175W

R=?

$p = \frac{ {v}^{2} }{r} \\ \\ 175 = \frac{ {220}^{2} }{r} \\ \\ 175r = 48400 \\ \\ r = \frac{48400}{175} \\ \\ r =</strong><strong>2</strong><strong>7</strong><strong>6</strong><strong>.</strong><strong>5</strong><strong>7</strong><strong>$

$r = 276.57$
