If the galvanometer G does not show any deflection in the circuit shown, the value of R is given by (figure-dependent: circuit with a 10V cell and 400Ω resistor in one branch, a 2V cell in another branch, both meeting at a node connected through galvanometer G, with variable resistor R between the node and the bottom rail — not transcribable as text)
