In some circumstances, you may need electricity but only have access to the phase wires of an AC main; if the neutral wire is not available, you need a neutral wire to use electricity for lighting a lightbulb or other electrical device. As you may already be aware, the earth can be used just like […]
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
Metals are well known for their ability to conduct electricity and heat, but have you ever stopped to think why they conduct electricity? In this article we will explore the science behind why metals are such a very good conductors of electricity and how conductivity works? In simple words, metals conduct electricity because they have
A semiconductor is a type of material that is commonly used in the construction of electronic components or devices. Semiconductors are characterized by their ability to conduct electricity under certain conditions; are crucial for the function of a wide range of technologies, including computers, smartphones, and solar panels etc. In this blog post, we will
This is something you shouldn’t do at all, but in this article, we will understand how it’s possible to touch a live wire without getting hurt! This may seem something impossible but in actuality it is possible. If you understand the science behind this and how actually electricity works then you can do the impossible.
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
