...s the batteries are in parallel (rarely used that way). Nearly all battery circuits are in series (which you can tell if their polarity is reversed one from another within the battery compartment). The resistance of a weak battery in a series circuit is the same no matter where it is in the circuit....
...but you’re not so excited about keeping strong acids around to etch your circuit boards, this simple DIY recipe uses common household chemicals in lieu of strong acid. 电子爱好者斯蒂芬霍布利想看看他是否能创造一种蚀刻溶液,而不是危险和有毒的气味在传统的盐...
开关与断路器 与保险丝类似,断路器用于保护特定房屋或建筑物的电气系统。电流过载有时会发生,如果你没有安装什么东西来保护你免受突然的电流冲击,你可能最终会损坏电器和其他敏感的电子设备。也许,最糟糕的事情...
...失有关。 什么是电位差(potential difference)? In an electrical circuit, the potential difference between any two points in the circuit is the energy lost by a coulomb of charge as it travels between those two points. Potential difference can be measured using a voltmeter, and it is exp...
... in one direction. As the electr*** flow through various components in the circuit, they lose their electrical energy. DC power refers to the amount of energy dissipated per second by a coulomb of electr***, as they travel between two points in a circuit. In a DC circuit, if a component has a po...
... different types of inductors When an inductor is connected to an electric circuit, a current flows through the coils in the conductor. Since magnetic fields form around moving charges, a magnetic field forms inside the coil. If the magnetic flux through the coil is given by , and if the coil has...
设置电路板的布局和设计可能很困难,但适当的电路板设计程序可能会使任务更容易。大多数电路板由不同数量的零件制成,因此大型零件库可能使电路板设计程序更有用...
电路板是一块绝缘材料,由导电导线和类似部件穿过。当电源向电路板引入电荷时,电荷会以各种方式沿这些导线分布到不同的组件。这使电路板能够控制在使用电气设备...
洗衣机电路板是一种印刷电路板(PCB)——一种带有控制机器的电气部件的电路板——其功能通常类似于洗衣机的大脑。洗衣机执行的几乎所有功能都由电路板控制。简单...
