Lesson Plan of Types of Electric Circuits (Parallel & Series Circuits)

General Science Grade VII

Students’ Learning Outcomes

·         Define current.

·         Make parallel in addition to serial circuit.

·         Investigate well-nigh types of circuits, used for unlike purposes.

·         Identify the disadvantages of serial circuit.

Information for Teachers

·         Electric Current: Flow of electrons passing through a conductor per mo is called electrical current. It is measured inwards Amperes (A) or mille ampere (mA).

·         Circuit: The path followed past times the electrical flow is called circuit.

·         Basic components: Basic components for an electrical circuit are battery, key/switch, bulb in addition to connecting wires.

·         The electrical components may live on connected inwards ii ways; serial combination in addition to parallel combination.

·         The types of circuit: There are basically 3 types of circuit 1. Series, 2 parallel, 3 serial in addition to parallel circuit.

·         Series circuit: inwards a serial circuit, accuse has entirely 1 path through which it tin flow. If 1 bulb burns out inwards a serial circuit, it becomes an opened upward circuit. The bulb inwards serial circuit is a root of resistance. Adding bulbs to a serial circuit increases the resistance. The electrical flow decreases in addition to each bulb smoothen less brightly.

Material / Resources

Dry jail cellular telephone (1.5V), jail cellular telephone holder, electrical bulb, bulb holder, connecting wires in addition to switch

Worm upward activeness

Development

Sum upward / Conclusion

        Q1. What is serial circuit?

        (Expected response: When ii or to a greater extent than bulbs are connected 1 afterward the other inwards such a agency that   

    A same electrical flow menstruum through all the bulbs is called serial circuit.

        Q2. What is parallel circuit?

       (Expected response: When ii or to a greater extent than bulbs are connected to each other inwards such a agency that the

         Current flows through unlike paths are called parallel circuit).

·         When the circuit is opened upward (either past times opening the key, broken wire, fused bulb or exhausted cell) the bulb doesn’t glow.

·         The electrical flow flows entirely when the circuit is closed.

Assessment

1.       What is the constituent of a switch?

(Expected response: To opened upward or closed the circuit)

2.       Name the root of electrical unloose energy inwards the circuit.

(Expected response: Cell or battery)

3.       Metal wires are used equally connecting wires. Why?

(Expected response: Metals are proficient conductor of electricity)

4.       Name the electrical equipment inwards the house.

(Expected response: Bulb, Tube light, Fan, T.V., Computer, Air conditioner)

Follow up

·         Draw circuit diagrams to connect 3 bulbs inwards diverse ways in addition to let on the characteristics.
