often appear in our lives. For example, electric heaters, electric water heaters, induction cookers and other household appliances have electric heaters, which are electronic devices that convert electrical energy into thermal energy. So how does it work? How does it work? Let's take a look next.
The electric heater is mainly based on the thermal effect principle of current. What is the current thermal effect? That is, a phenomenon in which the temperature of a conductor rises when current passes through various conductors, which converts electrical energy into internal energy, but the conversion rate is difficult to reach 100%. Among them, the resistance type electric heater is the most common type of electric heater in our lives. Because the current passes through the conductor to overcome the resistance of the conductor to do work, and the conversion of energy is measured by doing work, so as much work as current does, there is as much Electrical energy is converted into thermal energy. With a large resistivity, a resistance wire of a certain diameter will continuously heat up, thereby generating a thermal effect. This is an electric heater.
