We construct a series circuit and a parallel circuit consisting of several resistors and a DC power supply, and measure Ohm’s law and Kirchhoff’s law by measuring voltage and current at each point of the circuit.
Principle of experiment:
1) Ohm's law Metal conductors have conduction electrons. The thermal motion of conduction electrons is irregular and does not cause a net current, but when an external electric field is applied, the conduction electrons move in the opposite direction of the electric field. This motion causes a current in the conductor. Ohm's law can be written as "The ratio of the potential difference and the current between two points of the metal conductor at a constant temperature is constant." This constant ratio is called the electrical resistance R between two points, and the unit is Ω (ohm). Therefore, if the potential difference (voltage) between the two ends of the conductor is ΔV and the current is I, then Ohm's law can be written as
