Capacitive and inductive reactance in ac circuits | Physics, Mathematics and Chemistry Online Academy

In this video Chris demonstrates an experiment with inductive reactance in an electrical circuit. The setup includes a 12V power supply, a momentary switch, a 68-ohm resistor, a lamp, and a three-henry inductor. The host shows how current behaves differently through a resistor versus an inductor. First, the resistive lamp lights up as expected. When the inductor is added, the second lamp lights up more slowly due to inductive reactance, causing the current to "lag" behind. This delay occurs beca

Reactance in Antennas Explained! Understanding XL, XC, and Why it Matters for SWR! Following on from Antenna Impedance, we now explore Reactance – the second crucial component of that electrical opposition! What exactly is Reactance, where does it come from in your antenna, and why is it a major factor in SWR and tuning? This reel breaks down this essential concept for every ham radio operator. In this video, we cover: Defining Reactance: The opposition to changes in current or voltage caused by

This simulation compares how voltage behaves across a resistor, inductor, and capacitor when all three are driven by the same 1 kHz AC source. The oscilloscope above shows three distinct waveforms, each representing the voltage across one of the components. For the resistor, the voltage is exactly in phase with the current, producing a clean sinusoidal waveform with no phase shift. In the inductor circuit, the voltage leads the current by 90°, resulting in the waveform shifting left compared to
