·实验预习·１．把＿、＿、＿用导线＿组成的电流的路径叫做电路．用符号表示＿的图，叫做电路图． ２．合上开关，电路接通，电路中就有＿．＿叫做通路．＿的电路叫做开路．直接把导线＿上，电路中会有很大电流，可能把＿，这种情况叫做短路．实验中绝不允许将电源接成＿． ?

·Experimental preparations 1. The path of the current composed of _, _, and _ is called a circuit. A diagram with a symbol _, called a circuit diagram. 2. Close the switch, the circuit is connected, there is _ in the circuit. _ called the path. The circuit of _ is called open circuit. Directly on the wire _, there will be a large current in the circuit, may be called _, this situation is called a short circuit. Never allow the power supply to be connected in the experiment. ?
