tv antenna

It is a pair of point charges with equal magnitude and opposite in sign separated by a distance. Many physical systems from molecules to TV antenna can be described as electric dipoles. A water molecule is an example of an electric dipole. Even though the water molecule as such ..

A few examples of Transmission Lines Transmission lines are everywhere and are of infinite variety but regardless of type, length, or construction, all operate according to the same basic principles. Typical transmission lines include coaxial cable, a two-wire line, a parallel-plate or planar line,..

. A good quality service can be continuously ensured by a global operational satellite system. Thus, communication satellites would give a valuable service in addition to the submarine cable and high frequency radio systems. Geostationary communication satellites have enabled not only national but ..

>This frequency for which the current in AC circuit reaches a peak value and the A.C circuit behaves like a pure resistive circuit is called resonant frequency. The following diagram shows the variation of frequency with I o . Notice that as the value of R decreases, the value of I o increases. Sin..
