The reason of error in the experiment of verifying the correctness of Thevenin's theorem and Norton's theorem May I ask why there may be errors when doing experiments to verify the correctness of Thevenin's theorem and Norton's theorem

First of all, the instruments we use have errors. For example, the voltage source and current source of the test box all have internal resistance, and the resistance provided by the test box also has errors. When the circuit is connected, the node may have resistance, and when measuring, the internal and external connection of the voltmeter will also have an impact

How to use Thevenin's theorem and Norton's theorem to calculate the current in 24 ohm resistance
 

(1) Thevenin's theorem UAB = 32 - 2 * 8 = 16 vr0 = 8 Ω I = UAB / (8 + 24) = 0.5 A (2) & nbsp; Norton's theorem is = 16 / 8 = 2 ar0 = 8 Ω I = 2 * 8 / (8 + 24) = 0.5 A
