Superconductors are materials that can conduct direct current with zero resistance, when they are cooled below a specific temperature known as the critical temperature or Tc. In other words, when electric current is passed through a superconductor, it will flow without experiencing any resistance to flow of current, unlike normal conductors which will encounter resistance …

I was tired of constantly replacing the batteries in my multimeter, so I modified it to be rechargeable. Now, the battery lasts for about 2-3 months before needing to be charged again. Many newer Multimeters have an always-on backlight, which can drain the batteries quickly. However, with the modification I made, the battery lasts much …
