Web29 de dez. de 2012 · Dec 23, 2012. #2. It works because an alternating current is present in a pair of conductors which produces alternating electric and magnetic fields. Depending … Web18 de dez. de 2024 · We can express the total work done by the torque in rotating the dipole as. 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.

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.

WebFigure 1.4.4 – Torque on a Dipole. Multiplying the forces by the moment arms, and summing, we find that the magnitude of the torque on this dipole is: (1.4.2) τ = 2 [ q E d 2 sin θ] = q d E sin θ. The magnitude of the dipole moment appears in the equation, as does the strength of the electric field, and the sine of the angle between them.

WebIon - Dipole Interactions. A hydrogen bond is an intermolecular force (IMF) that forms a special type of dipole-dipole attraction when a hydrogen atom bonded to a strongly electronegative atom exists in the vicinity of another electronegative atom with a lone pair of electrons. Intermolecular forces (IMFs) occur between molecules.
