Effects of Electric Current

 Did you know that electric current has different effects? In this Blog Post, we are going to explore the three effects of electric current: the heating effect, the magnetic effect, and the chemical effect.

Heating effect of electric current: When electric current passes through a conductor, it produces heat, which is known as the heating effect of electric current. Electric bulbs produce light as the current flows through their filaments. Such bulbs are known as incandescent bulbs. Sandwich makers, geysers, and some electric kettles also use this phenomenon. In ancient engineering, a device called a fuse was used for safety, which worked with the heating effect of electric current. A fuse is a glass cylinder with metal edges, and a thin metal wire connects both the metal edges from inside. This wire melts when excess current flows through it due to the heating effect of electric current, and the circuit opens. Nowadays, fuses are replaced by MCBs (Miniature Circuit Breakers) as we no longer need to replace the fuse every time it melts.

Magnetic effect of electric current: A current-carrying conductor produces the same effect as produced by the magnetic field of a magnet. This effect of current is called the magnetic effect of electric current. If you want to read more about the magnetic effect of electric current, visit techumination.blogspot.com.

Chemical effect of electric current: When current is passed through a conducting liquid, it causes some chemical reactions. To understand this concept, let us perform an experiment. First, take two iron nails, a wide glass or plastic container, some saturated salt (full of salt) water, a few wires, and a battery. Make a circuit by connecting the iron nails to both terminals of the battery with wires, making sure that the two iron nails do not come into direct contact with each other, and place them in the water. After 3-4 minutes, do you notice gas bubbles near the iron nails? Near the nail connected to the positive terminal, the bubbles are oxygen, and near the nail connected to the negative terminal, the bubbles are hydrogen.

A Journey Through Display Technologies

Welcome to the world of display technology, where screens are more than just visual platforms. They are a blend of science and art, bringing images to life in vibrant colours and sharp contrasts.  From the sandwich-like structure of LCDs and LEDs to the firefly-like pixels of OLEDs and AMOLEDs, each screen type has its own unique story and characteristics. Whether it’s the affordability of LCD/LED screens, the stunning colour and contrast of OLEDs, the brightness of QLEDs, or the flexibility and speed of AMOLEDs, there’s a display for every need and budget. So, let’s dive in and explore these fascinating technologies together. LCD (Liquid Crystal Display) : Think of LCD as a sandwich. The “bread” is two layers of glass and the “filling” is a layer of special liquid crystals. These crystals can either let light through or block it, which helps create the picture on the screen. LED (Light Emitting Diode) : LED is just a fancy version of LCD. It’s still a sandwich, but instead of usin...

Understanding Credit Cards

Hey there, everyone! Let's talk about credit cards. Let's make it simple so it's super easy to understand. It all started when I asked my parents about credit cards. I was curious if the card companies charged interest like banks do on loans. They said no, and they also told me about the cool perks their cards offer. This got me thinking about how it all works and how the card companies make money. My curiosity led me to research more about credit cards, which inspired me to write this blog. What is a Credit Card? A credit card lets you borrow money from the bank to buy things, which you pay back later. But you must remember to return the money. How Do Credit Cards Work? Spending Limit: You can only spend up to a certain amount. Monthly Bill: At the end of the month, you get a bill showing how much you’ve spent. Paying Back: If you pay the full amount by the due date, you won’t be charged any extra money, called interest. What’s Interest? Interest is extra money the bank ch...
