## Single Phase Rectification

Rectification converts an oscillating sinusoidal AC voltage source into a constant current DC voltage supply by means of diodes, thyristors, transistors, or converters. This rectifying process can take on many forms with half-wave, full-wave, uncontrolled and fully-controlled rec...

## Transmission Gate

The analogue switch is a solid-state semiconductor switch that controls the transmission path of analogue signals. The open and closed operations of the switch positions are usually controlled by some digital logic network, with standard analogue switches available in many styles...

## Bus Transceiver

A Transceiver can be used to provide bidirectional, input or output control, of either digital or analogue devices to a common shared data bus. Unlike the buffer, transceivers are bidirectional devices which allow data to flow through them in either direction. Thus their name "t...

## Binary Fractions

We know that decimal (or denary) numbers use the base ten (base-10) numbering system where each digit in a decimal number is allowed to take one of ten possible values in the range of 0 to 9. So moving from right to left along a decimal number, each digit will have a value ten ti...

## Kirchhoff’s Voltage Law

Gustav Kirchhoff's Voltage Law is the second of his fundamental laws we can use for circuit analysis. His voltage law states that for a closed loop series path the algebraic sum of all the voltages around any closed loop in a circuit is equal to zero. This is because a circuit lo...

## Kirchhoff’s Current Law

To determine the amount or magnitude of the electrical current flowing around an electrical or electronic circuit, we need to use certain laws or rules that allows us to write down these currents in the form of an equation. The network equations used are those according to Kirchh...

## Resistivity

Ohms Law states that when a voltage (V) source is applied between two points in a circuit, an electrical current (I) will flow between them encouraged by the presence of the potential difference between these two points. The amount of electrical current which flows is restricted ...

## Thermistors

The Thermistor is a solid state temperature sensing device that acts a bit like an electrical resistor but is temperature sensitive. Thermistors can be used to produce an analogue output voltage with variations in ambient temperature and as such can be referred to as a transducer...
