Bridge Rectifier.

For most alternative energy applications, we require a direct current (DC) voltage to be generated – for example to charge a bank of batteries. However wind turbines and wave power generators create an alternating current (AC) voltage. This is where the Bridge Rectifier comes in. The AC voltage generated is passed through a circuit of […]

Diode.

What is a Diode? A diode is a p-n junction semiconductor, that allows current to flow in only one direction. A p-type semiconductor is a semiconductor, which only has positively charged holes. The n-type semiconductor, is one which has electrons or negatively charged carriers. The p-type and n-type semiconductors are diffused into each other to […]

Transistor.

The transistor, invented by three scientists at the Bell Laboratories in 1947, rapidly replaced the vacuum tube as an electronic signal regulator. A transistor regulates current or voltage flow and acts as a switch or gate for electronic signals. A transistor consists of three layers of a semiconductor material, each capable of carrying a current. […]

What is ARM Processor

The ARM processor is a 32-bit RISC processor, meaning it is built using the reduced instruction set computer (RISC) instruction set architecture (ISA). ARM processors are microprocessors and are widely used in many of the mobile phones sold each year, as many as 98% of mobile phones. They are also used in personal digital assistants […]

Transformer

A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled electrical conductors. A changing current in the first circuit (the primary) creates a changing magnetic field. This changing magnetic field induces a changing voltage in the second circuit (the secondary). This effect is called as mutual induction. If […]

Capacitors

Capacitor

Capacitors are components that are used to store an electrical charge and are used in timer circuits. A capacitor may be used with a resistor to produce a timer. Sometimes capacitors are used to smooth a current in a circuit as they can prevent false triggering of other components such as relays. When power is […]

Resistors

resistor

Resistor is a passive component used to control current in a circuit. Its resistance is given by the ratio of voltage applied across its terminals to the current passing through it. Thus a particular value of resistor, for fixed voltage, limits the current through it. They are omnipresent in electronic circuits. The most common type […]
