Solving Impedance Diagrams: Finding i(t) with XL = ωL

[k31453]

Homework Statement

Homework Equations

impedence diagram, XL = ωL

The Attempt at a Solution

Ok i got XL = 47 ohm
Then my phase angle is 88.8 degree.

Then to find i(t) i have to add that angle to the function right?

Your question isnot visible. Can you write it?

That's not quite right.

If you show your work maybe we can help find where things went wrong.

Convert the inductance to an impedance and add it to the resistance. You now have an equivalent circuit with the voltage drop across the impedance given. Use Ohm's law to find the current.

Remember ω = 2*pi*f
