Making 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 MORE

Electric 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 MORE

Wheatstone Bridge

This world is full of electrical sensors of varying types......READ MORE


Resonant 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 MORE


Ohm'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 MORE



When electricity was discovered, the initial belief was that current flowed from the positive terminal to the negative terminal. READ MORE


Bipolar Transistors

The two basic types of transistors in use today are the Bipolar Junction Transistor (BJT) and the Field Effect Transistor (FET). READ MORE


Op 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 MORE



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 MORE

More on Meters

Sooner or later, you will need to use a panel meter to show current or voltage.........READ MORE


Vacuum tubes – thermionic valves – have been around almost since the start of electronics, radio and wireless. READ MORE
