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.

In section 8.8 we learned that polar covalent bonds occur between atoms of different electronegativity (section 8.7), where the more electronegative atom attracts the electrons more than the electropositive atom, and based on the geometry, this may or … new tech trends

WebAs far as I can tell, the radiation patterns are nearly identical, with the v-dipole having slightly higher gain in front of the v than behind it. The main reason for the bend that I've found is impedance matching. A normal half wave dipole has an impedance of 73+j42.5 ohms, but when it is bent to 120° the impedance drops down to ~58 ohms. A short dipole is a dipole formed by two conductors with a total length ℓ substantially less than a half wavelength (1/ 2 λ). Short dipoles are sometimes used in applications where a full half-wave dipole would be too large. They can be analyzed easily using the results obtained below for the Hertzian dipole, a fictitious entity. Being shorter than a resonant antenna (half wavelength long) i… WebFan Dipole : How it works.
