Description

"Different Circuit Connections" Electrical PPT Courseware

A circuit is connected according to the needs of life and work. In such a circuit, various connection methods and electrical components are used.

Junction boxes are generally dark boxes.

Guess the function of the junction box:

A junction box is used as a transition at the joint of the wire, and the wires in the conduit are connected in the junction box.

1. Protect wires

2. Connect the wires

3. Easy maintenance

Four-connector circuit cassette detection

Use a circuit detector to check which terminals are connected to each other? Which terminals are open circuits?

Conclusion: Points A and D of this junction box are connected together.

Group Activity

1. Connect 2 batteries, 2 battery boxes, 1 small light bulb, and several wires to form a circuit to make the small light bulb light up. See who has more methods.

2. Observe and think about the different effects of different methods.

Which little light bulb is brighter?

Principle: The voltage of one battery is 1.5V, and the voltage of two batteries connected in series is 3V, so the small light bulb will be particularly bright. When two batteries are connected in parallel, the voltage is still 1.5V, so the small light bulb is not very bright.

Expansion activities: Whose design is the most distinctive?

Provide students with some materials, and work in groups to freely design circuits and compete to see whose design is the most unique and practical.
