The Human body can be damaged by current flowing......... READ MOREHall Effect Transistor
In 1879 Edwin Hall, an American physicist, explored the interaction......... READ MORESmith Charts
A Smith Chart appears complicated, cluttered, and unintelligible to the newcomer. So let us break it down. READ MOREDecibels
The first time most people hear the expression dB is in relation to sound. Looking at a noise chart..... READ MOREMaking Sence of Circuits
Making sense of a circuit diagram, for the first time, may seem to be a daunting task. This article will break down the process of reading a simple circuit diagram into logical steps. READ MOREElectric Shock
The human body can conduct electricity and is susceptible to electrical shock. Electrical shock can range from mild tingling to severe burns and even death. The high voltage is not normally fatal as demonstrated by coming into accidental contact with the spark plug lead of a motor car. READ MOREWheatstone Bridge
This world is full of electrical sensors of varying types......READ MOREResonant Circuits
An important element of any radio communications equipment is the LC circuit. L is the inductance measured in Henries (H) and named after Joseph Henry (1797–1878). The symbol L for inductance was chosen to honour Heinrich Lenz (1804-1865) who pioneered work in electromagnetic induction. READ MOREOhm's Law
In 1827 a German physicist, Georg Ohm, published a paper on his electrical experiments. The result is Ohm’s Law and the identification of electrical resistance that bears his name. READ MOREDiodes
When electricity was discovered, the initial belief was that current flowed from the positive terminal to the negative terminal. READ MOREBipolar Transistors
The two basic types of transistors in use today are the Bipolar Junction Transistor (BJT) and the Field Effect Transistor (FET). READ MOREOp Amps
The operational amplifier (Op Amp) is one of the most versatile devices available, and applications using this device are wide spread in both the analogue and digital arenas. READ MOREMulti-Meters
Ever wondered how your trusty analogue voltmeter works? A lot goes on inside the meter, but it is all based on Ohm’s Law. READ MOREMore on Meters
Sooner or later, you will need to use a panel meter to show current or voltage.........READ MOREValves
Vacuum tubes – thermionic valves – have been around almost since the start of electronics, radio and wireless. READ MOREDigital Signal - Foundation
