Electrical Circuit

An electrical circuit is a loop which provides a path for electric current (electric charge) to flow. This loop must be closed. In other words, the current must be able to flow from positive to negative terminals otherwise the flow will not take place. The charge is made possible by a source such as a […]

Conductors, Insulators, Semiconductors

Conductors: Conductors are the materials that easily allow flow of electric current upon application of voltage, such as copper. Conductivity is the measure of how easily current will flow through that material and shown by the symbol σ (sigma). Its unit is Siemens / meter (S/m) but usually milliSiemens / meter is used. It is […]

Sensors and Transducers

Sensors and transducers can sometimes be confused because they both react to some change in their environment but they are not the same thing. SENSOR A sensor is a component in an electronic system that can detect (sense) various types of changes in the physical environment and as a result, communicate these to the bigger […]

Analog vs. Digital Electronics

We can look at electronics in two different ways, both of which have different uses, which are analog vs. digital electronics. In short, analog electronics deals with continuous, smoothly varying signals, and digital electronics is about handling discrete signals (which are either on or off or in other words, 1 or 0). ANALOG ELECTRONİCS In […]
