👉 Bromometric, also known as a thermocouple or thermistor, is a type of electronic circuit that converts electrical signals into heat, typically in the form of light. It consists of two parallel metal plates (usually copper) and an insulator between them. The basic principle behind a thermocouple is based on the concept of thermal resistance. When hot electrons are accelerated through the gap between the two metal plates, they create a current in the thermocouple wire. This current causes
