1.	The arms consisting of the resistances R1 and R2 are called _________(a) resistance arms(b) impedance arms(c) source arms(d) ratio armsThis question was addressed to me during an online exam.Query is from Wheatstone Bridge Balance Condition in section Measurement of Resistance of Electrical Measurements
Answer» Right answer is (d) ratio arms For explanation I would SAY: The arms consisting of the two resistances R1 and R2 are known as the resistance arms. SOURCES do not appear on the arms of the bridge and they are connected across OPPOSITE ends. Wheatstone bridge is purely resistive in NATURE.
