Even though the modern electric utility industry didn’t begin until the late 1800s, we have been fascinated by electricity since our ancestors first witnessed lightning. So here are a few ideas for projects. The simplest experiment with electricity might be an exploration of conductors versus insulators. A conductor is simply a material through which electricity will flow with little resistance; an insulator prevents electricity from flowing. This can be tested by creating a simple circuit with a battery and a light bulb. If a material completes the circuit, the light bulb will luminesce, indicating that it is a conductor. Most metals are conductors, while most nonmetals are insulators. Therefore, it will not be a surprise to see that silver and copper are conductors, while cotton and glass are insulators. However, you may be surprised by the results of lead (a metal) or graphite (a non-metal). Epoxy molding engineering plastics mainly … Read the rest

Business – small or large – now flourishes online. Mobile phones have made everything cheap and accessible. Time is gone when people travel from place to place just to pass information to people. Today, within a twinkle of an eye, information reaches the receiver because mobile phones are available. This will be particularly pronounced in smaller, cost-conscious companies that now run on a mix of licensed and unlicensed Windows PCs. Instead of gaining a few more desktop licenses, Microsoft may end up losing the entire company to open source software. Some countries are heavily invested in nuclear energy and it is a major source of power for millions of people across the world. Those in favor of it say it is Green because it burns clean and doesn’t directly send emissions into the air. Those against it point out the serious problems faced in storing radioactive waste for many generations … Read the rest
