The open-circuit saturation curve (also open-circuit characteristic, OCC) of a synchronous generator is a plot of the output open circuit voltage as a function of the excitation current or field. The curve is typically plotted alongside the synchronous impedance curve .
The voltage v oc between the terminals is the open-circuit voltage of the device. Black curve: The highest possible open-circuit voltage of a solar cell in the Shockley-Queisser model under unconcentrated sunlight, as a function of the semiconductor bandgap. The red dotted line shows that this voltage is always smaller than the bandgap voltage.
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.
Gavin is the largest coal-fired power facility in Ohio, [1] and one of the largest in the US, capable of powering two million homes. In February 2017, the plant represented slightly more than 11% of the total electric generation capacity in Ohio according to the Energy Information Administration (EIA). [ 2 ]
The source end of the line is approximately an open circuit due to the high R S, [1] so the step is reflected uninverted and travels back down the line toward the load. The result is that a pulse of voltage is applied to the load with a duration equal to 2 D / c , where D is the length of the line, and c is the propagation velocity of the pulse ...
The open-circuit test, or no-load test, is one of the methods used in electrical engineering to determine the no-load impedance in the excitation branch of a transformer. The no load is represented by the open circuit, which is represented on the right side of the figure as the "hole" or incomplete part of the circuit.

Then, temporal discretization is used to replace the derivatives with differences, such as ′ (+) + + for the backward Euler method, where h n+1 is the time step. [5]: 266 If all circuit components were linear or the circuit was linearized beforehand, the equation system at this point is a system of linear equations and is solved with ...
