    Power Supplies & Transformers

    Power supplies are devices which swap one type of electrical energy to another. Whilst transformers transmit the same type of energy between two or more circuits. Both power supplies and transformers can range in sizes and are found within everyday items. As an example, power leads to computers or games consoles will take AC voltage from the mains and input that into a power supply. This will then change to DC output voltage and power the appliance, completing the circuit.

    Transformers cannot change voltage types, they will only operate on an AC voltage to build a changing magnetic field. With no direct electrical connection with the primary and the secondary coils.
