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
Two Wire Sensor Working Principle and Animation
Sensors can also be broken down by their wiring configurations. The most common are 2-wire and 3-wire. Two-wire devices are
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
Circuit Elements and Types of Circuits
A circuit element is an idealised mathematical model of a two-terminal electrical device that is completely characterised by its voltage-current
What is a PLC? – Programmable Logic Controller
A Programmable Logic Controller, also called a PLC or programmable controller, is a computer-type device used to control equipment in an industrial facility.
Digital Building Blocks – GATES
GATES are DIGITAL BUILDING BLOCKS. They are called DIGITAL because they operate on digital principles. They require a signal (also
Transformer Open and Short Circuit Tests
We conduct open circuit and short circuit test on single phase transformer to determine the efficiency and regulation of a
