Why is the circuit configuration known as a Wheatstone bridge?

(N/A) The circuit is called a Wheatstone bridge because it was invented by $Samuel \text{ } Hunter \text{ } Christie$ in $1833$ and later improved and popularized by $Sir \text{ } Charles \text{ } Wheatstone$ in $1843$. The term 'bridge' is used because the galvanometer acts as a bridge between the two parallel branches of the circuit, allowing for the detection of current flow when the potential difference between the two midpoints is non-zero.
