WebAboutTranscript. Dipole–dipole forces occur between molecules with permanent dipoles (i.e., polar molecules). For molecules of similar size and mass, the strength of these forces increases with increasing polarity. Polar molecules can also induce dipoles in nonpolar molecules, resulting in dipole–induced dipole forces. WebA resonant coax-fed dipole antenna will have a low SWR and will radiate efficiently on the band for which it is resonant, but it will not work well on all bands. For example, if the tuning range of your tuner has a sufficient range, you will be able to load up any antenna with it, but it will not necessarily radiate a signal efficiently.

W = ∫ θ i θ f τ z d θ, where τ z = p E sin θ. If, in the above derivation, I assumed the opposite direction for the field, i.e. E → is replaced with − E →, a clockwise torque would occur and the work done on the electric dipole would be. golf grip too thick

WebA Balun is used to "balance" unbalanced systems - i.e. those where power flows from an unbalanced line to a balanced line (hence, balun derives from balance to unbalanced).As an example, consider a coaxial cable connected to a half-wave dipole antenna shown in Figure 1. Figure 1. An unbalanced transmission line (coaxial cable) connected to a dipole antenna. WebDipole-Dipole interactions result when two dipolar molecules interact with each other through space. When this occurs, the partially negative portion of one of the polar molecules is attracted to the partially positive portion of the second polar molecule. This type of interaction between molecules accounts for many physically and biologically ... Web3 de jan. de 2011 · http://www.antenna-theory.com presents the analysis of the dipole antenna!
