I got the same answer as you. I did not follow every step of your work. While the angle does round to 90 degree, I think it's important to know that it can never equal 90, and will be slightly less.

You got the same answer regarding the value of the current as well?

Mentor
Your current magnitude and angle are both correct.

magnuol
Your current magnitude and angle are both correct.
Does it seem accurate that the order of the real component (a) is 10^(-7) when the imaginary component (b) is that much bigger?

Mentor
Yes. That's why the phase angle is so close to 90°.

For whatever it's worth, I got the same real and imaginary parts for the current as @magnuol .
