What is the current in a circuit that has a power of 200 W and a resistance of 150 Ω

Respuesta :

Answer:

Current = 1.15 A

Explanation:

Since we are finding the current

Power in a circuit can be found by using the formula

[tex]P = I ^{2} R[/tex]

Where

I is the current

R is the resistance

P is the power

From the question

Power = 200 W

Resistance = 150 Ω

Substitute the values into the above formula and solve for the current

That's

[tex]200 = 150{I}^{2} [/tex]

Divide both sides by 150

We have

[tex] {I}^{2} = \frac{200}{150} \\ = \frac{4}{3} [/tex]

Find the square root of both sides

We have

[tex]I = \sqrt{ \frac{4}{3} } [/tex]

= 1.154700

We have the final answer as

Current = 1.15 A

Hope this helps you
