A popular electrical component used on many control circuits is the step-down transformer. It is the power source for a separate lower-voltage circuit which typically controls the operation of a ...

step-down transformers decrease the voltage. The transformer in the diagram above is a step-down transformer – there are fewer turns on the secondary coil than on the primary coil. Type of ...

Using electromagnetic induction, a transformer transfers electrical energy between two or more coils to step voltage up or down, ensuring power can be efficiently transmitted over long distances ...
