Kinetic exospheric models similar to those developed for the polar wind have been used to determine the current density as a function of the electrostatic potential difference. In the upward current region of the auroral zone, the current–voltage relationship depends on the number density and ...
Discover the relationship between tube voltage and tube current in X-ray technology. The voltage applied across the X-ray tube determines the energy spectrum.
To determine the phase relationship between voltage and current in an AC circuit containing only an inductor, we can follow these steps:Step 1: Understand the Voltage and Current Equations In a purely inductive circuit, the vol
Inductorsdo not have a stable “resistance” as conductors do. However, there is a definite mathematical relationship between voltage and current for an inductor that you can think of asOhm's lawfor an inductor: v=Ldidtv=Ldidt Where:
Ohm’s lawis one of the basic principles of electricity. It relates the basic parameters of electricity, current and voltage, to each other. Georg Ohm, after whom the law was named, conduct a few experiments on circuits containing different lengths of wires and found that the voltage applied...

A flux-controlled memristor characterized by smooth cubic nonlinearity is taken as an example,upon which the voltage-current relationships(VCRs) between two parallel memristive circuits-a parallel memristor and capacitor circuit(the parallel MC circuit),and a parallel memristor and inductor circuit(the ...
resistance is similar for equal currents of either polarity, and decreases with increasing intensity. The voltage produced by a constant current greater than 300μA falls in a few seconds to 1·8 V at the cathode, and 2·8 V at the anode. Non-linearity is less marked using 20 c/s ...
