Mutual inductance occurs when the change in current in one inductor induces a voltage in another nearby inductor. It is important as the mechanism by which transformers work, but it can also cause unwanted coupling between conductors in a circuit. The mutual inductance,, is also a measure of the coupling between two inductors.
1 Multi-capacitance systems and mutual capacitor. Of an ac network, a linear capacitor C, when supplied with an ac voltage source across its terminals, is described as i = C (dv /dt) [], which characterises the i − v relationship between its two terminals or between a single conductor and somewhere at infinity in system; where C is its symbol and also denotes its …

A capacitor is a device that stores energy. Capacitors store energy in the form of an electric field. At its most simple, a capacitor can be little more than a pair of metal plates separated by air. As this constitutes an open circuit, DC current will not flow through a capacitor. If this simple device is connected to a DC voltage source, as ...

This ''mutual inductance'' is the basis for the electrical transformer that is ubiquitous in the electric power industry. Transformers, with their impedance transforming property are also useful in electronic circuits over almost the entire frequency spectrum. We will not cover all these uses in this experiment but will mainly concentrate on the resonant circuit with inductor and capacitor ...
Mutual Inductance in Coils: These coils can induce emfs in one another like an inefficient transformer. Their mutual inductance M indicates the effectiveness of the coupling between them.

A capacitor is a device which stores electric charge. Capacitors vary in shape and size, but the basic configuration is two conductors carrying equal but opposite charges (Figure 5.1.1). Capacitors have many important applications in electronics. Some examples include storing electric potential energy, delaying voltage changes when coupled with
With the switch disconnected, the capacitor was charged to a voltage V m and then at the moment t = 0 the switch was closed. Find: (a) the current I (t) in the circuit as a function of time; (b) the emf of self-inductance in the coil at the moments when the electric energy of the capacitor is equal to that of the current in the coil.
To sum up, whether the changeable parameter is the mutual inductance or the load, the estimated results of the load and mutual inductance are basically close to their actual values. Meanwhile, the output voltage can be estimated effectively based on the estimated results of the load and mutual inductance. This has proved the effectiveness of the proposed …

While lowering mutual inductance may sound good, recall that, in this special case, the signal and return current''s mutual inductance is being used to cancel the inductance. Lowering the mutual inductance lowers the cancellation. The signal "sees" the inductance of the entire loop, including both the inductance of the signal trace and the inductance of the …

14.2: Mutual Inductance Inductance is the property of a device that tells us how effectively it induces an emf in another device. It expresses the effectiveness of a given device. When two circuits carrying time-varying currents are close to one another, the magnetic flux through each circuit varies because of the changing current in the other circuit. Consequently, an emf is …
