[" The potential difference between points "A],[" and "B" is- "],[qquad [,2V,1Omega],[," A "]],[qquad [,-1longmapsto_(1),1Omega],[4sqrt(12)]]

Resistance R_1 and R_2 , each 60 Omega , are connected in series. The Potential difference between points A and B is 120 V . Find the reading of voltmeter connected resistance r=120Omega

In the network shown the potential difference between A and B is R(=r_(1)=r_(2)=r_(3)=1Omega,E_(1)=3V,E_(2)=2V,E_(3)=1V)

Four resistors R_(1),R_(2),R_(3) and R_(4) are connected between two terminals A and B iin a network as shown in the diagram. A key K can connect the two points (see diagram) C and D. A constant potential difference (V_(A)-V_(B))=V is maintained between thhe points A and B Q. If R_(1)=R_(4)=1Omega and R_(2)=R_(3)=2Omega , the effective resistance between the terminals A and B will change, on closing the key K, by

Four resistors R_(1),R_(2),R_(3) and R_(4) are connected between two terminals A and B iin a network as shown in the diagram. A key K can connect the two points (see diagram) C and D. A constant potential difference (V_(A)-V_(B))=V is maintained between thhe points A and B Q. If V=25,R_(1)=1Omega,R_(2)=2Omega,R_(3)=3Omega and R_(4)=4Omega the current that will flow from C to D on connecting key K is

In the network shown the potential difference between A and B is (R = r_(1) = r_(2) = r_(3) = 1 Omega, E_(1) = 3V, E_(2) = 2V, E_(3) = 1V )
