In a balanced wheatstone bridge, current in the galvanometer is zero. It remains zero when:1. battery emf is increased2. all resistances are increased by \(10 \mathrm{ohms}\)3. all resistances are made five times4. the battery and the galvanometer are interchanged 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
