5J20.23  EFFECT OF INDUCTOR IN CIRCUIT



  • 2 identical bulbs in separate circuits have the same current flowing through them.
  • When the switch is closed, the bulb in series with the coil turns on more slowly.









        (use 2 - 12 V, 50 W bulbs)
        (match the current in both circuits, bulbs should glow with equal brightness)


  • Version 2
  • 2 identical bulbs are connected in parallel, but 1 bulb has an inductor in series.
  • When the switch is closed, the bulb in series with the coil turns on more slowly.
  • Limit ON time to 15 seconds to keep the coil from overheating.

        (use 2 - 12 V, 15 W bulbs and green 16 ohm coil)
        (match the current in both circuits, bulbs should glow with equal brightness)
