Problem

A bridge circuit has resistances

R_{1} = 100\,\Omega

R_{2} = 200\,\Omega

R_{3} = 50\,\Omega

, and

R_{4} = 25\,\Omega

arranged in a standard diamond. A battery of

10\,\text{V}

is connected across the input terminals. Determine the potential difference between the galvanometer terminals (

V_{B} - V_{D}

) and state the direction of current if a galvanometer were connected.
