Electric Coils Power Pages
Electric Coils
An electric coil, or electromagnetic coil, is an electrical conductor that contains a series of conductive wires wrapped around a ferromagnetic core that is cylindrical, toroidal, or disk-like. Electric coils are one of the simplest forms of electronic components and provide...
Electromagnetic Coils
An electromagnetic coil is an electrical coil that generates an electromagnetic field when electric current passes through it. The structure of an electromagnetic coil consists of a length of wire that is wound around a core, which can be a cylinder, bobbin, oval, or other...
Inductor and Inductor Coils
Inductors are passive two terminal components of an electric or electronic circuit that are capable of storing energy in magnetic form. They oppose sudden changes in current and they are also called coils or chokes...
Solenoid Coils
A solenoid coil is a common electrical component that uses a wire that is tightly wrapped around a core, usually made of metal, to generate an electromagnetic field. When an electrical current is passed through the coil, the electromagnetic field that is created provides energy for linear motion...
Toroidal Inductors
Toroidal inductors are passive electrical components that store energy in a magnetic field and resist changes in a current as electricity passes through it. They consist of insulated wires that are wound around a coil that has a donut shape...
Voice Coils
A voice coil is a winding of a wire, usually copper, aluminum, or copper-clad aluminum that is wrapped around a former (often called a bobbin) and then attached to the apex of a speaker cone...
Electric Transformers
Electric transformers are static electrical machines that transform electric power from one circuit to the other without changing the frequency. An electrical transformer can increase or decrease the voltage with...
Isolation Transformers
An isolation transformer, just like typical transformers, is a non-moving device that transmits electrical energy from one circuit to another without requiring any physical contact. It works on the idea of magnetic...
Three-Phase Transformers
An electrical transformer is a passive machine that transfers electrical energy from one circuit to another using a magnetic flux to induce an electromotive force. Transformers are used to increase (step-up) or decrease (step-down) voltages without changing the frequency of the electric current...
