WebDefinition: The effect in which the voltage at the receiving end of the transmission line is more than the sending voltage is known as the Ferranti effect. Such type of effect mainly occurs because of light load or open circuit at the receiving end. Ferranti effect is due to the charging current of the line. WebThe Hall voltage does not indicate the flow of charge (current), but the strength of the charge. This static charge increases or decreases according to the density of charged particles (or charge “carriers”) flowing past the the edges that are transverse to the flow of the bias current.
