What is a circuit? The circuit is the path for the flow of current (just like the water flow requires a river, the circuit is equivalent to the river, the current is equivalent to the river water), its role is to transmit and distribute electrical energy, and make electrical energy and other forms of energy mutual conversion (such as electrical energy Converted into heat energy to boil water or heat, etc.).
