How do digital cameras work?

On the surface, many digital cameras could easily be mistaken for traditional cameras. Both have lens, viewfinders, zoom features, and various buttons and gadgets neatly packed into a square package. However, even the smallest inspection of a digital camera would immediately demonstrate its place in twenty-first-century technology. Digital cameras rely on three unique components that […]

How Electromagnets Work

An electromagnet is just like any other magnet and will attract certain metals (iron and steel) and other magnets. The difference is an electromagnet only works when electricity is flowing through it. So what components make up an electromagnet and how does it work? In this article, we will answer those questions as we look […]

How capacitors work

Electricity is seamlessly integrated into our lives like nothing else. Many do not understand how the many different components operate in order to manipulate electricity into a useful thing. Capacitors are one of these key components that we use to control electricity. To understand how a capacitor works, it is helpful to understand how a […]

How an electric generator works

Faraday’s Law of Induction is the principle under which electric generators work. Every magnet has a field of waves around it. Electric current is generated if this magnetic field is disturbed. The electric current can flow along a closed loop of wire. The magnetic field is disturbed by any form of physical motion or force. […]

How Inductors Work

Let us first begin down this winding path of coiled electronics by explaining what an inductor is. The construction of the inductor is from a piece of conductive wire–usually copper. The conductive property of wire is merely a term that is used for how well the free electrons of an element, in this case copper, […]
