Voltage Dividers

Voltage Divider Circuits are useful in providing different voltage levels from a common supply voltage. This common supply can be a single supply either positive or

Current Dividers

Current Divider Circuits are parallel circuits in which the source or supply current divides into a number of parallel paths. In a parallel connected circuit, all

Current Sources

As its name implies, a current source is a circuit element that maintains a constant current flow regardless of the voltage developed across its terminals as this

Voltage Sources

We have seen throughout this Basic Electronics Tutorials website that there are two types of elements within an electrical or electronics circuit: passive elements and active elements. An active element

Star Delta Transformation

We can now solve simple series, parallel or bridge type resistive networks using Kirchhoff´s Circuit Laws, mesh current analysis or nodal voltage analysis techniques but in

Nortons Theorem

Norton on the other hand reduces his circuit down to a single resistance in parallel with a constant current source. Nortons Theorem states that “Any linear

Thevenin’s Theorem

In the previous three tutorials we have looked at solving complex electrical circuits using Kirchhoff’s Circuit Laws, Mesh Analysis and finally Nodal Analysis. But there
