What is simplified equivalent circuit?
The equivalent circuit model is derived by simplification of the original fifth-order equivalent circuit, based on the fact that the resonant capacitor behaves like an equivalent resonant inductor with respect to the modulation frequency. …
What is the equivalent circuit of Earth?
This paper gives a method of equivalent charge for calculate and represent the electric field around the three-phase lines and the current which will be induced in the objects near the high voltage transmission lines.
What are waveguides?
A waveguide is a structure that guides waves, such as electromagnetic waves or sound, with minimal loss of energy by restricting the transmission of energy to one direction. The original and most common meaning is a hollow conductive metal pipe used to carry high frequency radio waves, particularly microwaves.
What is an equivalent circuit diagram?
Equivalent circuit diagram of a transformer is basically a diagram which can be resolved into an equivalent circuit in which the resistance and leakage reactance of the transformer are imagined to be external to the winding.
What are the two requirements for a circuit to be electrically equivalent to another circuit?
To be analyzed as a two port network the currents applied to the circuit must satisfy the port condition: the current entering one terminal of a port must be equal to the current leaving the other terminal of the port.
What do we do with equivalent circuit?
Equivalent circuits can be used to electrically describe and model either a) continuous materials or biological systems in which current does not actually flow in defined circuits, or, b) distributed reactances, such as found in electrical lines or windings, that do not represent actual discrete components.
What are H parameters of BJT?
hix = hie – The input impedance of the transistor (corresponding to the emitter resistance re). hrx = hre – Represents the dependence of the transistor’s IB–VBE curve on the value of VCE. It is usually very small and is often neglected (assumed to be zero). hfx = hfe – The current-gain of the transistor.
Which mode is not allowed in waveguide?
TM mode: Transverse magnetic waves, also called E waves are characterised by the fact that the magnetic vector (H vector) is always perpendicular to the direction of propagation. TEM mode: The Transverse electromagnetic wave cannot be propagated within a waveguide, but is included for completeness.
What are a circuits two requirements?
There must be an energy supply capable doing work on charge to move it from a low energy location to a high energy location and thus establish an electric potential difference across the two ends of the external circuit.
What makes circuits equivalent?
In electrical engineering and science, an equivalent circuit refers to a theoretical circuit that retains all of the electrical characteristics of a given circuit. In its most common form, an equivalent circuit is made up of linear, passive elements.
