In electrical engineering, a transformer is a passive component that transfers electrical energy from one electrical circuit to another circuit, or multiple circuits.
Transformers do what their name implies—they transform voltages from one value to another (The term voltage is used rather than emf, because transformers have internal resistance).
5 sie 2023 · Explains the theory, construction, installation, and maintenance of transformers and the different types of transformers before going on to cover related power devices such as circuit breakers, fuses, and protective relays.
Learn about and revise transformer function and design, the transformer equation, and power calculations in transformers with GCSE Bitesize Physics.
The iron core of a transformer is normally a complete ring with two coils wound on it. One is connected to a source of electrical power and is called the primary coil ; the other supplies the power to a load and is called the secondary coil .
12 mar 2024 · Transformers do what their name implies—they transform voltages from one value to another. For example, many cell phones, laptops, video games, and power tools and small appliances have a transformer built into their plug-in unit (like that in Figure \(\PageIndex
13 wrz 2024 · Transformer, device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the voltage. Transformers are employed for widely varying purposes.
