Dependent Sources An ideal source, either voltage or current, whose value depends upon some parameter (usually a voltage or current)…

Current Divider Rule

8 years ago

It can be quite useful to determine how a current entering two parallel resistors “divides” between them. Consider the circuit shown…

It can be quite useful to determine how a voltage appearing across two series resistors “divides” between them. Consider the…

Combining Independent Current Sources in Parallel

8 years ago

It is not possible to combine independent current sources in series, since this would violate KCL. However, consider the parallel…
