I'm in the AC text book on chapter 11 under power factor. The question I have is regarding the image/link below.

If S=Apparent Power= I²(Z), then how does that = 169.256?

Wouldn't Z = XL + R

Z = 60.319 + 60

Z = 120.319

Then S = I²(Z)

S = 1.410²(120.319)

S = 1.9881(120.319)

S = 239.206 ?

*I'm not getting 169.256 as shown in the textbook and image below. Even when applying pythagorean theory I'm unable to come up with the answer given.

Can you please tell me where I am going wrong on this?

*True power, reactive power, and apparent power for a resistive/reactive load.*
