It’s a great way of learning electronics. And what do we have nowadays? Snap circuits! At that time, I could never even dare to think about other ways of getting into the world of electronics. In short, when I was a kid, I learnt electronics in a classic way: I connected wires, added all the necessary components and even made my own electronic exploration kits. If you look around, you will see that electric circuits are everywhere, and they are powering all kind of things around you: trucks, fridges, washing machines, phones, computers and many other home appliances that use electric power to work. The electricity leaves the bulb and flows back through the battery. As the electricity goes through the bulb, the bulb lights up. In the situation with the flashlight that’s a light bulb. The circuit then leads to whatever we want to power. In most of the cases, such path is made by some kind of a wire. I have learnt that electricity flows from the power source on the path of the circuit. My Dad said, “Electricity is like a train on train tracks: when there’s no more tracks, the train stops”. In a circuit, if electricity doesn’t have a path to travel on, it stops. In order to get there, the electricity had to go along a specific path. However, the electricity didn’t simply jump from the battery to the bulb. And when the electricity went through the bulb, the flashlight lit up. My Dad told me that in case of the flashlight, the electricity to the light bulb came from the batteries that were inside. By that time, I didn’t know a lot about the electricity that powered various items in our house. The question that kept me up for a lot of time was what really made the light go on? Later my Dad explained that it was electricity that made the light go on. All I had to do was to move a switch or press a button, and the light came on! Yes, I loved to switch it on and off, but I hadn’t got an idea why it was that way. ![]() I didn’t understand how a flashlight worked.
