Series circuit and parallel circuit are two circuits composed of different connection methods. Process and method: 1. Use the circuit detector to check the connection of the circuit in the junction box. 2. Try to connect the circuit with different methods, and find the characteristics of different connection methods through repeated observation and experiment. Emotional attitudes and values: 1.
