在日常生活中,我们离不开用电器,也离不开电,但每个用电器内部线路流经的电流却不尽相同.计算器中的电流约为100μA,半导体收音机中的电流约为50 mA,手电筒中的电流约为200 mA,家庭节能灯中的电流约为0.1 A,家用电冰箱中的电流约为1 A,家用空调机中的电流约为5 A,在雷电交加之时的电流可以达到20 000 A.既然电流有强有弱,那么我们又该用什么工具测量电流的大小呢?测量电
In everyday life, we can not do without electricity, but also can not do without electricity, but the flow of electricity through the internal circuit of each appliance is not the same.The current in the calculator is about 100μA, the current in the semiconductor radio is about 50 mA, the current in the flashlight is about 200 mA, the current in the household energy-saving lamp is about 0.1 A, the current in the household refrigerator is about 1 A, the current in the household air conditioner is about 5 A, When the current can reach 20 000 A. Since the current is strong and weak, then what should we measure the current size of the current? Measuring electricity
