If a circuit schematic contains a current source, is it safe to assume I(total) is that value?
gabjew90 said:Just in general. How would I go about finding total current if a current source is present?
A current source is an electrical device that generates and supplies a constant current to a circuit. It is typically represented by a symbol with an arrow pointing away from the source, indicating the direction of the current flow.
A voltage source provides a constant voltage to a circuit, while a current source provides a constant current. This means that the voltage across a current source may vary depending on the resistance of the circuit, while the current remains constant.
The total current in a circuit with multiple current sources is the sum of the currents from each individual source. This is known as Kirchhoff's Current Law, which states that the total current entering a junction in a circuit must equal the total current leaving the junction.
Yes, a current source can be used to power a circuit with varying resistance. The current source will automatically adjust its voltage to maintain a constant current, regardless of the changes in resistance.
Current sources are commonly used in electronic devices such as transistors, amplifiers, and LED drivers. They are also used in industrial applications, such as powering motors and controlling the flow of electricity in power grids.
