An electric iron is rated at 1000watts, 250v. The corresponding maximum resistance and accompanying current is

A.

62.5A, 4.0\(\Omega\)

B.

16.0A, 62.5\(\Omega\)

C.

62.5A, 16.0\(\Omega\)

D.

4.0A, 62.5\(\Omega\)

E.

4.0A, 250\(\Omega\)

Correct answer is D

R = \(\frac{V^2}{R}\) = IV ; R = \(\frac{V^2}{P}\) and I = \(\frac{P}{V}\)

R = \(\frac{(250)^2}{100}\) and I = R = \(\frac{1000}{250}\)

R = 62.5\(\Omega\) and I = 4A
