The aim of the research was to analyze the electrical conductivity of the obtained coal from organic material by pyrolysis. In order to take measurements of the electrical properties of the biochar, a prototype device was built. In addition to measurements of electrical properties, it enables measurement of the specific density of any sample of bulk material. In the case under consideration, after filling the working chamber and concentrating the powder, a carbon pellet was obtained. For it, direct electrical properties were determined by direct measurements, ie: voltage drop at the current flow through the sample (direct and alternating current), resistance of the carbon resistor, value of current flowing through the resistor, inductance and capacity. In addition, the dynamic characteristics of the voltage with respect to the alternating current flowing through the carbon resistor were recorded using the oscilloscope. It has been noted that capacitive features can be attributed to the test samples.
