Description:
A step up transformer is built 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 reduces 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.
