What are the basic principles of electricity?
Get to grips with electricity and electrical theory with this brief introduction of the basic princples. At its simplest, electricity can be described as a form of energy brought about by charged particles either statically, or through charge or current. Essential to understanding where electricity comes from and what it is, you first need to gain a simple understanding of atomic theory. All matter is formed of atoms, which can…

An introduction to transformers
This article serves as an introduction to transformers and the theory behind them. What is a transformer? A transformer is a device that increases or reduces the voltage of an alternating (AC) current.   What is the principle of Mutual Inductance? A transformer works on the principle of Mutual Inductance. This is the principle that a change in the current of one coil on a conductor will affect the current…

How does an MCB work?
This excerpt from ABB introduces the technology inside and miniature circuit breaker (MCB). What does an MCB do? The short answer: it protects wires from overloads and short-circuits. When we look on the inside of an MCB we can see how that actually works. For overload protection the temperature of a bimetal, through which the current passes (yellow area), is decisive. If the nominal current—the current the circuit breaker is…
