A circuit for measuring electrical properties such as the resistance, capacitance and inductance includes two bridge branches each having at least two serially-connected components which can comprise resistors, capacitors and inductors or combinations thereof. One of the components is variable with respect to its resistance by means of a quantity which is under measurement. The bridge branches are connected to different voltage outputs of a common alternating current supply. The diagonal points between serially-connected components in each of the bridge branches serve as measuring points for a measurable signal. Each measuring point may be connected by a line having a rectifier followed by a capacitor forming an electronic store such that at the output of the stores there is a direct current potential forming the measurable signal.
