Current Divider Rule
It can be quite useful to determine how a current entering two parallel resistors “divides” between them. Consider the circuit shown
Voltage Divider Rule
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
It is not possible to combine independent current sources in series, since this would violate KCL. However, consider the parallel
Combining Independent Voltage Sources in Series
Combining Independent Sources An inspection of the KVL equations for a series circuit shows that the order in which elements
Series and Parallel Resistors
Combining Resistors Relatively complicated resistor combinations can be replaced by a single equivalent resistor whenever we are not specifically interested
What is Kirchhoff’s Voltage Law
Starting at any node in a circuit, we form a loop by traversing through elements (open-circuits included!) and returning to
What is Kirchhoff’s Current Law
A connection of two or more elements is called a node. An example of a node is depicted in the
Short Circuit and Open Circuit
The Short-Circuit Consider a resistor whose value is zero ohms. An equivalent representation of such a resistance, called a short-circuit,
Basics of Ohm’s Law
In 1827 the German physicist George Ohm published a pamphlet entitled “The Galvanic Circuit Investigated Mathematically”. It contained one of
