Answer:

Current = 1.15 A

Step-by-step explanation:

Since we are finding the current

Power in a circuit can be found by using the formula


P = I ^(2) R

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


200 = 150{I}^(2)

Divide both sides by 150

We have


{I}^(2) = (200)/(150) \\ = (4)/(3)

Find the square root of both sides

We have


I = \sqrt{ (4)/(3) }

= 1.154700

We have the final answer as

Current = 1.15 A

Hope this helps you
