Electricity is a natural phenomenon that occurs throughout nature and takes many different forms. In this tutorial we’ll focus on current electricity: the stuff that powers our electronic gadgets. Our goal is to understand how electricity flows from a power source through wires, lighting up LEDs, spinning motors, and powering our communication devices.
An electron traveling through the wires and loads of the external circuit encounters resistance. Resistance is the hindrance to the flow of charge. For an electron, the journey from terminal to terminal is not a direct route. Rather, it is a zigzag path that results from countless collisions with fixed atoms within the conducting material.
With great power comes great responsibility. No, no, I’m not talking about Mr. Peter Parker. I’m talking about electricity, one of the most convenient and useful items in homes today. In fact, I bet you’re using electricity right now! Whether you’re charging your laptop, watching TV, or just using a lamp, you’re making use of the wondrous wonder that is electricity. But with electricity’s power comes a great potential for harm. If you don’t use electricity properly, you’re liable to end up shocked, aflame, or worse.
Battery technology lags far behind the technology it powers. As a result, the sole area in which portable devices are stagnant is their battery life.
For many people, electricity is still quite mysterious and the concept of saving electricity is quite abstract. For example, we all know that we should turn lights off when we leave a room to save electricity but this is at odd with how we feel. Having a bright room makes us feel safer, warmer and happier, even if we are wasting electricity. Even if you don’t know your amps from your volts, here are four tips that will help you save electricity effortlessly.
