Open Circuit and Short Circuit | Ultimate Electronics Book

The open circuit voltage is the voltage difference measured between two terminals when no current is drawn or supplied. The short circuit current is the current that flows when the terminals are forced to have zero voltage difference. We''ll use these two values in Thevenin Equivalent and Norton Equivalent Circuits.

Mineral Flotation

Open-circuit test

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.

What is Open Circuit Voltage?

Open Circuit Voltage Represents a Voltage Source''s Full Voltage Because it doesn''t drop any voltage across a load, as what would happen when it is connected to a load, a voltage source''s open circuit voltage represents its full voltage value, since the voltage doesn''t share any of its voltage with a load.
