Come up with a device that allows you to automatically signal that the maximum temperature has been reached with the help of an electromagnetic relay, a thermometer and a bell. Draw a circuit diagram for this device.
When the temperature rises to a certain level. mercury rises and closes the contacts that are in the thermometer. The circuit is closed, voltage is applied to the relay coil, the relay closes the contact, voltage is applied to the bell, which rings and signals that the temperature limit has been reached.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
