Conductors and Insulators of Electricity A major reason electricity works is because of conductors. First metal‚ water‚ tall trees and tall items are good conductors because lightning is attracted to them. These materials have many mobile electrons. Metal is an easy substance for lightning to travel through so metals are good conductors. However‚ rubber is a bad conductor because lightning bounces off of it. A bad conductor is called an insulator. An insulator has a few mobile electrons. It is

The radiation may vary between 250 and 265 nm (corresponds to maximum in DNA absorption spectrum). It is very effective in germicidal action‚ against bacteria and virus. The lamps are called germicidal lamps‚ bactericidal lamps or UVC lamps. Blue

4G Wireless Networks: Data and Bandwidth Improvements How much faster is 4G compared against 3G? The speed of 3G networks depends on how they are implemented. By 2010 Verizon (a CDMA network) had reached the limits of its 3G network speed in the United States. 4G networks allowed Verizon the ability to offer transmission speeds up to four times faster than its current 3G network. AT&T’s 3G network‚ however‚ is based on GSM. The GSM design left AT&T room to upgrade its current 3G speeds
