#98 - Inductive Reactance Demonstration - Frequency Up, Ohms Up

How frequency affects the “ohms” of an inductor — inductive reactance. Inductive reactance increases with frequency, meaning the inductor resists current flow more as the frequency rises. At zero hertz (DC), the inductor looks like a simple wire (zero ohms), allowing current to pass freely. This video demonstrates how increasing frequency causes a light bulb to dim, because the "ohms" of the inductor (its reactance) increases — reducing current through the circuit.

Why does inductive reactance cause a phase shift between voltage and current? This video shows how the current lags the voltage in an inductive circuit, and explains why this happens in practical terms.
