Question

Does inductance depend on current, frequency, or both? What about inductive reactance?

a) Inductance depends on current; inductive reactance depends on frequency.

b) Inductance depends on frequency; inductive reactance depends on current.

c) Both inductance and inductive reactance depend on current.

d) Both inductance and inductive reactance depend on frequency.

Answer 1

Inductance depends on current and inductive reactance depends on frequency.

Step-by-step explanation:

Inductance depends on the current flowing through the inductor and the magnetic field it produces, while inductive reactance depends on the frequency of the AC voltage applied to the inductor.

For inductance, the equation is given by L = Φ / I, where L is the inductance, Φ is the magnetic flux, and I is the current. Inductance is measured in henries (H).

For inductive reactance, the equation is given by XL = 2πfL, where XL is the inductive reactance, f is the frequency, and L is the inductance. Inductive reactance is measured in ohms (Ω).
