Methods and apparatuses for obtaining electrical characteristics and moisture content of dried objects having different shapes and sizes through impedance and electrostatic capacity measurements are provided. Measuring the moisture content of dried objects comprises the steps of: introducing dried objects of different sizes and shapes into a container, inserting four electrode terminals into the container, measuring electrical characteristics between two electrodes based on the dried objects and inputting measurement results into a high impedance voltmeter. An apparatus is provided comprising: a container for accommodating dried objects having different sizes and shapes, four electrode terminals inserted into the container, an AC signal having a predetermined voltage to be applied to the terminals, and a high impedance voltmeter for measuring and receiving electrical characteristics between two terminals based on the dried objects.
