Capacitor - Wikipedia
A capacitor is a device that stores electrical energy in an electric field by virtue of accumulating electric charges on two close surfaces insulated from each other. It is a passive electronic component with two terminals.. The effect of a capacitor is known as capacitance.While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor …
RLC Circuit - Wikipedia
In this circuit, the three components are all in series with the voltage source.The governing differential equation can be found by substituting into Kirchhoff's voltage law (KVL) the constitutive equation for each of the three elements. From the KVL, + + = (), where V R, V L and V C are the voltages across R, L, and C, respectively, and V(t) is the time-varying voltage from the source.
Memristor - Wikipedia
A memristor (/ ˈ m ɛ m r ɪ s t ər /; a portmanteau of memory resistor) is a non-linear two-terminal electrical component relating electric charge and magnetic flux linkage.It was described and named in 1971 by Leon Chua, completing a theoretical quartet of fundamental electrical components which comprises also the resistor, capacitor and inductor. ...
Resonance - Wikipedia
Resonance describes the phenomenon of increased amplitude that occurs when the frequency of an applied periodic force (or a Fourier component of it) is equal or close to a natural frequency of the system on which it acts. When an oscillating force is applied at a resonant frequency of a dynamic system, the system will oscillate at a higher amplitude than when the same force is …

Resistor - Wikipedia
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.High-power resistors that can dissipate many watts of electrical power as heat may be …

Phasor - Wikipedia
Phasor notation (also known as angle notation) is a mathematical notation used in electronics engineering and electrical engineering. can represent either the vector (, ) or the complex number + =, with =, both of which have magnitudes of 1. A vector whose polar coordinates are magnitude and angle is written .. The angle may be stated in degrees with an implied …
How To Measure Current Using Current Sensors | Dewesoft
The IOLITE 6xSTG features six differential inputs with over-voltage protection and sensor power from each of its universal inputs and sample rates up to 20 kS/s/ch. For current measurements, It has a built-in 50 Ω shunt resistor that can be applied in software, allowing engineers to measure current either up to 2 mA or 20 mA, user-selectable.
