What is the typical voltage used by a doorbell?

The typical voltage used by a doorbell is 12 volts. This standard voltage is commonly used for low-voltage doorbell systems, which are designed to operate safely with less electrical power than traditional household wiring. Using 12 volts helps to reduce the risk of electrical shock, making it suitable for installation near entryways where moisture may be present.

Many doorbell transformers convert household voltage (usually 120 volts) down to this lower level, ensuring that the electrical system is safe for consumers while still providing adequate power to ring the chime effectively. Other voltages listed might be used in specific applications or older systems, but 12 volts has become the standardized voltage in modern doorbell installations due to its safety and efficiency benefits.
