Reaction of Secondary on Primary
# 5K30.60


Description: A light bulb is in series with the primary of a transformer. As the resistance across the secondary of the transformer is increased, the current through the primary decreases. The amount of current flowing through the primary is illustrated the intensity of light bulb and in this case it does not glow as brightly.

Purchased/Built: built

Setup Time: none

Quant. in Demo Room: 1

Demo References
Sutton E-241 Connect a 100 W lamp in series with the primary and increase the load on the secondary to light the lamp.
Freier and Anderson Em-2 A light bulb in series with the primary brightens as the load on the secondary increases.
