List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
Phasor notation (also known as angle notation) is a mathematical notation used in electronics engineering and electrical engineering.A vector whose polar coordinates are magnitude and angle is written . [13] can represent either the vector (, ) or the complex number + =, according to Euler's formula with =, both of which have magnitudes of 1.
Numerical Methods: Employed for simulating and solving complex circuits that cannot be solved analytically. Used in computer-aided design tools for electronic circuit design. Vector Calculus: Applied in electromagnetic field theory. Important for understanding the behavior of electromagnetic waves and fields in electronic devices.
The faults may be three-phase short circuit, one-phase grounded, two-phase short circuit, two-phase grounded, one-phase break, two-phase break or complex faults. Results of such an analysis may help determine the following: Magnitude of the fault current; Circuit breaker capacity; Rise in voltage in a single line due to ground fault
The magnitude of a complex number is the length of a straight line drawn from the origin to the point representing it. The Smith chart uses the same convention, noting that, in the normalised impedance plane, the positive x -axis extends from the center of the Smith chart at z T = 1 ± j 0 {\displaystyle \,z_{\mathsf {T}}=1\pm j0\,} to the ...
The field produced by a single-phase winding can provide energy to a motor already rotating, but without auxiliary mechanisms the motor will not accelerate from a stop. A rotating magnetic field of steady amplitude requires that all three phase currents be equal in magnitude, and accurately displaced one-third of a cycle in phase.
The complex gain G of this circuit is then computed by dividing output by input: G = 2 V j ⋅ 1 V = − 2 j . {\displaystyle G={\frac {2\ V}{j\cdot 1\ V}}=-2j.} This (unitless) complex number incorporates both the magnitude of the change in amplitude (as the absolute value ) and the phase change (as the argument ).
In power engineering, the power-flow study, or load-flow study, is a numerical analysis of the flow of electric power in an interconnected system. A power-flow study usually uses simplified notations such as a one-line diagram and per-unit system, and focuses on various aspects of AC power parameters, such as Voltage, voltage angles, real power and reactive power.
