What is applied to the two opposite junctions of a bridge circuit?(a)

1.	What is applied to the two opposite junctions of a bridge circuit?(a) source of voltage(b) source of current(c) source of power(d) source of impedanceThe question was asked by my school principal while I was bunking the class.Asked question is from Introduction of Bridges topic in chapter Measurement of Resistance of Electrical Measurements
Answer» The correct OPTION is (b) source of CURRENT Explanation: A current source is connected between the two OPPOSITE junctions of a bridge circuit. Deflection of the galvanometer in the circuit indicates the flow of current.
