Household current is typically 120 volts for most circuits. A few circuits, such as those for electric clothes dryers, require 240 volts. Since doorbells have such a low voltage requirement, they need a means of converting 120 volt current down to the 8 to 24 volts necessary to operate the chime. Thatâs where a step-down transformer comes in. Higher voltage electricity arrives at the transformer, where it flows through wiring coiled around an iron core.
