5J20.20 Energy of an Inductor
Energy of an InductorA lightbulb is put in series with a large coil. As you remove the metal core from the coil, the energy from the inductor travels through the circuit illuminating the lightbulb.
5J20.20 Series vs Parallel (AC Circuit)Three identical light bulbs in series and three identical light bulbs in parallel show the fundamental difference between parallel and series circuits.
5J20.20 Series vs Parallel (AC Circuit) - Different Bulbs
The finished product, demonstrating the bulbs in series.
The finished product, demonstrating the bulbs in series.
Series vs Parallel (AC Circuit) - Different BulbsTwo simple circuits employing three lightbulbs of different wattages in series and in parallel further exemplify the differences between parallel and series circuits.
5J20.20 Series vs Parallel (DC Circuit)
The finished product, demonstrating the bulbs in parallel.
The finished product, demonstrating the bulbs in parallel.
Series vs Parallel (DC Circuit)Using a DC power supply and 3 light bulbs of identical wattage explain properties of parallel and series circuits.
5J20.26 LR Decay
LR DecayObserve the periodic decay of an inductor's voltage using an oscilloscope.
