Excite a Circuit: Wheatstone Bridge Strain Gage Application

[ghostdog]

What is meant by excite a circuit?

My question is what is the excitatoin voltage of a wheatstone bridge? Is this the minimum voltage that needs to be applied across the wheatstone bridge.

I'm looking at a strain gage application for a wheatstone bridge.

Thanks for the super help. This is my first posting!

"Exciting" just means applying a voltage or current.
There is no minimum voltage (or current) as such for abridge, you can make it as small as you want. However, the signal-to-noise ratio will of course be smaller if you you a low voltage.
I.e. the only "limit" is your ability to read out the result.
