ON VIDEO Current Source vs Voltage Source

 

Current Source vs Voltage Source

A Source is a device that converts mechanical, chemical, thermal, or other form of energy properties into electrical energy. In other words, the source is an active network element intended to generate electrical energy. The different types of sources available in the electrical network are voltage sources and current sources. A voltage source has a forcing function of emf while the current source has a forcing current function.

The voltage source, ideally, has the same electrical voltage regardless of the load it is supplying. This is the case for 1.5 volt batteries, 12 volt batteries, and 230 volt AC sockets: whatever the load, the source voltage remains the same (… in an ideal universe).

The current source, ideally, offers an electric current of the same intensity regardless of the load in which it delivers its current. Current sources are scarce. Lightning is a current source, it creates a few hundred thousand amperes.

The transistor, in linear operation, is a current source. Certain generators on which the intensity can be assigned are false current sources: they modify the electric voltage permanently so that the output intensity is always the same.
