Question

The 4 arms of a wheatstone bridge in figure have following resistance AB=100ohm, BC=10ohm, CD=5ohm and BA=60ohm a galanometer of 15ohm resistance is connected across BD. Calculate the current through the galanometer when a potential difference of 10volt is maintained across AC?

Answer 1

Answer:

Use KVL for current distribution across each component as shown in circuit (see figure) and solve to get current through galvanomeRead more on Sarthaks.com - https://www.sarthaks.com/454538/the-four-arms-of-wheatstone-bridge-see-figure-have-the-following-resistance
