In the above figure, an a meter bridge , two resistances in the gap are 5 ohms and 10 ohms. The wire resistance is 10 ohms. The emf of the cell connected at the neds of the wire is 5 volts and it's internal resistance is 10 ohm.Show that the current flowing through the galvanometer of resistance 30 ohmsif the contact is made at the mid point of the wire is given by ig = 25 / 1357 A.
