Therefore, if five small bulbs are connected in series with a switch, the power supply, the switch and the five small bulbs are connected end to end in turn, as shown in the following figure:
How to judge whether the electrical appliances in the circuit are connected in series or in parallel?
Series connection and parallel connection are two basic forms of circuit connection, and there are some differences between them. To judge whether the components in the circuit are connected in series or in parallel, we must master their basic characteristics. The specific method is as follows:
(1) Connection mode of electrical appliances: analyze the connection mode of electrical appliances in the circuit and connect them in series one by one; Parallelism between two points in a circuit is parallel.
(2) current direction method: when the current flows out from the positive pole of the power supply, it flows through all components in series; When the two branches flow to somewhere separately and finally come together, it means that the circuits are connected in parallel.
(3) Disassembly method: Remove any electrical appliance to see if other electrical appliances are working normally. If all electrical appliances have been removed and other electrical appliances can continue to work, then the connection relationship of these electrical appliances is parallel; Otherwise, it is series connection.
