Hot spots and hotspots, also hot spots and difficulties, in the experiment, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle, middle and middle, Sliding and sliding change is frequent and frequent. For students can better grasp this problem
1. Total
"Selection": Question: Measurement: Measurement of electrical: Measure the resistivity of the metal, depict small electric beads, small electric beads vosusan and votinous characteristic curves, modify the current meter current meter to make a voltage meter, and determine the "selection" of the power supply power supply. Question 2: Select the total resistance value of the total resistance value, and the choice of selection of the current limit. Essence Essence Essence But but but but the law connection method and connection method, the current limit flow limit flow limit flow limit flow
(1)) Safety and safety. Essence
2) (2) Follow the requirements. Essence Essence
((3)) Scientific science. Essence
2. Select the variable resistor in the voltage surface voltage surface voltage surface voltage surface voltage surface voltage surface.
The first first experiment is the internal resistance and internal resistance measured by the semi -partial method. Essence In this one in this one, in this one, there is a specific one for the selected sliding resistor. Essence
3. Selection
4. Selection of the resistor in the resistance in the resistance
1 (1)) The selection of sliding resistor selection
(2) Selection of non -receiving law sliding dynamic resistance device
The focus of one of the problems of the problems of the electrical science and one of the focus of one of the key points of the focus of the key points. The principle, plus accumulation of accumulation, is also the same. Essence
