What is the equivalent circuit?

equivalent circuit is a simplified model of an existing district that significantly simplifies the analysis of the original district. Any circuit will have equivalent for specific parameters such as signal frequency, component temperature and other factors such as converter inputs. The original circuits may have a voltage source with internal resistance and several external resistors, while equivalent circuits, in direct current analysis (DC), will be a voltage source and a single internal resistance or pure resistance of internal and external resistors. There are equivalent circuits for all types of circuits with all types of components. As soon as the battery gets used to, the equivalent circuit is constantly changing until the battery passes. The ideal voltage source has no internal resistance and in the series with increasing resistance is equivalent to a real 1.5 V) battery (V).

transformers provide power by secondary winding when energy is provided in the primary winding. The transformer equivalent circuit helps to explain the detailed properties of the transforMator in the real world. The ideal transformer does not release any power unless there is any load on the secondary winding, but the real world transformer with an energized primary winding and the disconnected secondary winding will still release power. The equivalent circuit of the transformer due to the nature of the core loss will represent a parallel resistance of the core or resistance that does not exist but can be seen by the energy source. The circuit of the equivalent transformer has an ideal output transformer with more distributed induction, capacitance and input resistance.

equivalent circuits for semiconductor circuits vary depending on frequency, polarity voltage and amplitude of the signal. The equivalent of the Circuit diode in forward distortion or performing the state is a low -voltage source in a low resistance series. For example, a silicon diode in forward distortion may have an equivalent voltage source of 0.6 VDC V series with a resistor of 0.01 Ohm.

equivalent model circuit model for engines is also determined by RevoLucemi rotor per minute (RPM) and introduction torque. For example, a DC motor with a rotating rotor looks like two electromagnets in the equivalent motor circuit; At 0 rpm, DC engine attracts the most up -to -date. If the rotor is rotated to rotate, the clean distributed engine resistance increases towards the normal level, so the engine power drops to a normal level. When using torque, the engine current of the engine increases. The induction motor equivalent circuit includes the equivalent core resistance and distributed inductance, capacity and ideal transformer that controls the anchor winding.
