XL =2p x f x L.

Where:

XL = inductive reactance measured in ohms

2 = a constant (2 x 3.1416 = 6.28)

f = the AC frequency of the electrical supply in hertz

L = the inductance value of the coil in henries.

For those that don't get EM theory:

2 Pi is the circumfrence of a circle.

All wave and EM is based on the circle and then the phase of the wave and strength of the wave and then the resistance to the movement around the unit circle.

Then add one field is elecrtric 90 degrees from magneticic and it is the interaction that creates all fields in 3D and the result is a vector field of force between them.

can someone please explain Voltage leads current by 90 degrees?

ohh I get it — thanks use the sphere to visualize the concept

Therefore if the current is 90 degrees out of phase with voltage in 3D and 1.4 out of phase in 2D - does that mean the voltage is on the 90 degree magnetic field and related to the the influence of the magnetic field that causes the voltage - that would explain a lot.

because if I can link voltage to the magnetic field on the electric field it amakes sense - voltage dependant upon magnetic field and the all the oppositite effects of the fields click.

If it is the magneetic field that is primarily responsible for the voltage induced in the electric field every basically makes sense to me.

Inducttion resisstance and reactance.

Because if the influence of the magnetic field causes the voltage in the electrical field and then move one field or another a current will flow in one or other direction and that field will then create reactance to the primary electric and magnetic fuels I get !!!

no I just figured someone might be smarter than me in this thing.

voltage leads current by 90 degrees - shift phase in 2D but same phase in 3D/
