In a Wheatstone's brigde all the four arms have equal resistance R . If the resistance of the galvanometer arm is also R , the equivalent resistance of the combination as seen b the battery is

An ohm meter measures the resistance placed between its leads. This resistance reading is indicated by a galvanometer that operates on current. The ohm meter has an internal source of voltage to create the necessary current to operate the galvanometer and also has approproate resistor to allow just right amount of current through galvanometer. A simple ohm meter is shown here. When there is an infinite resistance, there is zero current through galvanometer and it points in middle. If the test leads of this meter are directly shorted, (zero resistance) galvanometer will give full deflection. Galvanometer specification Resistance of galvanometer = 100 Omega Fullscale current = 0.5 mA Total number of division =40 .

The instrument used to measure resistance is the Wheatstone bridge with a slide resistance-a wire of high resistivity of length L (Fig. 26.6). Here R is a calibrated resistance, R_x, the unknown resistance. By moving the sliding contact, the current in the galvanometer is made to drop to zero. Making use of this condition (of bridge balance), find the resistance being measured.
