Function:
Transformers are devices used in electrical circuits to change the voltage of electricity flowing in the circuit. Transformers can be used either to increase the voltage (called "step up") or decrease the voltage ("step down"). Transformers found in furnaces are "step down" transformers and usually convert 120-240 volt to 24 volt.
