Teaching You things that nobody does on Instagram: "People sometimes talk about a “melting” or heating pen made from everyday items, but what’s really being shown is the idea of electrical resistance turning energy into heat. When electricity flows through a material that resists it, that energy has to go somewhere — and it usually shows up as heat. In concepts like this, the pencil or metal isn’t special by itself. It’s just acting as a conductor with resistance, where electrical energy convert

Great minds🧠 on Instagram: "💡 Did You Know? A cut wire doesn’t always mean you need to call an electrician or spend extra money. With the right simple process, you can fix a cut wire properly, safely, and without risking an electric shock. Many people panic when they see a damaged wire, but basic electrical knowledge can help you save both time and money. This simple process focuses on fixing the wire the correct way using proper insulation, tight connections, and safety precautions. When done
