Question

How does inductive reactance relate voltage amplitude to current amplitude?

Options

• \[i_m=v_mX_L\]

• \[i_m=\frac{X_L}{v_m}\]

• \[i_m=\frac{v_m}{X_L}\]

• \[i_m=v_m+X_L\]

Answer 1

Since \[X_L=\omega L\], the amplitude relation becomes \[i_m=\frac{v_m}{X_L}\]. This mirrors Ohm's Law, with \[X_L\] playing the role of resistance.
