Phase Angles

[Shurbunkin]

Homework Statement

Im an apprentice electrition and my 2nd year principles exam is coming up. the question i ask is about Phase angles. It asks me to represent my data using a phase angle but in the book im using there are no equations to show me how to get my phase angle. im working on my inductance. it shows how much the current is leading the voltage. its all about being 'out of phase'

Homework Equations

the inductance equation is
XL=2pie(3.142)fL
XL - inductive reactance (ohms)
F - supply frequency (hertz)
L - Circuit inductance (henrys)

The Attempt at a Solution

i have attempted on the inductance equations but have not go any further. please help. im very confused

If you were to look at your input waveform and your output waveform, the distance between these would be your phase angle in pi-radians. I'm not sure what the title "electrician" means where you live.....are you familiar with transfer functions?
