Can we measure a resistance of the order of 0.160 Omega using a Wheatstone's bridge ? Support your answer with reasoning.

With the help of a labelled diagram, show that the balancing condition of a Wheatstone bridge is : (R_(1))/(R_(2))=(R_(3))/(R_(4)) where the terms have their usual meaning.

The resistance of the four arms A, B, C and D of a wheatstone bridge as shown in the figure are 10 Omega , 20 Omega , 30 Omega and 60 Omega respectively . The emf and internal resistance of the cell are 15 V and 2.5 Omega respectively . If the galvanometer resistance is 80 Omega then the net current drawn from the cell will be

The resistance of the four arms P, Q, R and S in a Wheatstone's bridge are 10 ohm 30 ohm and 90 ohm rerspectively. The e.m.f. and internal resistance of the cell are 7 V and 5 ohm respectively. If the galvanometer resistance is 50 ohm , the current drawn for the cell will be

What is the condition for the error in measuring resistance on a Wheatstone bridge to be a minimum? How can it be achieved?

Four resistence of 10 Omega, 60Omega,100Omega and 200Omega , respectively taken in order are used to form a Wheatstone's bridge . A 15 V battery is connected to the ends of a 200Omega resistance, the current through it will be
