In the everyday electrical devices we use — calculators, remote controls and cell phones — a voltage source such as a battery is required to close the circuit and operate the device. In this hands-on activity, students use batteries, wires, small light bulbs and light bulb holders to learn the difference between an open circuit and a closed circuit, and understand that electric current only occurs in a closed circuit.

    PCB assembly
    By the way, it is thanks to printed circuit boards that modern electronic devices have such small dimensions. Without printed circuit boards, they would have a much more impressive size. I read a lot of interesting things about it here https://www.pcbonline.com/PCB-Assembly/PCB-Assembly-Overview
