Exercises - Inductivity at AC voltage

Exercise 1 

An ideal coil with L = 35 mH is connected to an AC voltage with a frequency of f = 50 Hz. How big is the inductive reactance XL?

Exercise 2

An ideal coil with a reactive resistance of 6.3 kΩ is connected to a frequency of 60 Hz. Determine the inductance of the coil.

Exercise 3

A real coil has an ohmic resistance (wire resistance) and a reactance. To determine these two resistances, the coil (see measuring circuit) is connected to a DC voltage of 30 V and in the following to AC voltage of 50 V / 50 Hz. The current is 2.5 A each.
