而英文中的电(Electricity)在古希腊文的意思就是“琥珀”(amber)。希腊文的静电为(elektron) 近代探索 18世纪时西方开始探索电的种种现象。美国的科学家富兰克林(Benjamin Franklin,1706～1790)认为电是一种没有重量的流体,存在于所有物体中。当物体得到比正常份量多的电就称为带正电;若少于正常份量,就被称为带负...

Now we will show you how doeselectricityget produced when we rotate single loop of a conductor in amagnetic field. During rotation, when one side of the loop comes in front of the magnetic north pole, the instantaneous motion of the conductor will be upward hence according toFleming’s Right...
What is the working principle of a fan? Electric Motors Fans are made of an electric motor and rotor blades. The fan is usually a single-phase induction motor and the rotor blades are optimized aerodynamically. The fan uses electricity to rotate the blades which then drive air in the room...
Working Principle: The zener diode working principle involves a voltage-triggered breakdown that allows it to conduct electricity in reverse, providing a stable voltage regardless of input changes. Voltage Regulation: Zener diodes are essential for maintaining consistent voltage in electronic circuits, ensu...
