**Imagine the PCB (printed circuit board) as a city, where electricity is the traffic and traces (circuit paths) are the roads. The components (like resistors, capacitors, etc.) can be seen as different buildings, each with a specific function. Some are workplaces (like microprocessors), some are stores (like capacitors storing charge), while others regulate traffic (like resistors). The electricity, or traffic, begins its journey from the power source, the main highway (like the battery). It follows the traces or roads to reach different components or buildings. However, these roads are not all alike. Some are wide and allow a lot of traffic to flow quickly; these are the low resistance paths. Other roads are narrow and slow down traffic; these are high resistance paths. The rules of the road, like traffic signals and signs, are established by the design of the PCB and the components used. In some instances, the traffic might have to stop and wait (as in a capacitor building up charge), while in others it might get diverted to a different part of the city (as when a transistor switches). In the end, after performing their various tasks across the city, all the traffic eventually finds its way back to the highway, completing the circuit. This flow of traffic continues as long as the city or the circuit is powered.** - Image #4 <@710551916849004544>
