Hi all , last week my teacher told me to make a lab on wheatstone bridge but using a headphone as a galvanometer. If anyone have an idea about it please tell ): .

 

Hello,

You can power a wheatstone bridge with AC, like a tone generator.
When the bridge is in balance, you will hear nothing out of the headphone.

You can read more about bridges using the links of this page of the EDUCYPEDIA:
