Transformers - Freq Depend.gif

Description:

A demo that shows a transformer requires an alternating current to work. A step up transformer is set-up as shown. With the function generator putting out a 60 Hz sine wave to simulate commercial power, the light bulb lights up easily. As the frequency is reduced the brightness of the bulb also decreases until is eventually goes out altogether. A two channel oscilloscope can also be used to track the relationship between the input and output wave forms.
