Question

A power rating of an electric stove is 750W. Determine the current flowing through it if it's resistance is 1.5ohms

Answer 1

Answer:

I = √500 A = 22.5 A

Explanation:

Given r = 1.5 Ω

$power \: = {i}^{2} \times r$

${i}^{2} = \frac{power}{r}$

${i}^{2} = \frac{750}{1.5}$

${i}^{2} = 500$

$i = \sqrt{500} \: a$

$i = 22.5 \: a$
