Topic: Parallel and Series Connection Of Lighting Circuit.

1. Didactic Reflection

1.1 Curriculum Analysis:

The name of this course is residential installation ,the code of curse is ( ELT 182).

The trimester is 3. The hours of workshop are 6 hours. The hours of lecture are 2

hours. This practical course trains the trainee to plan, implement, buildings. It also

introduce the trainee to the residential circuit breakers and KWH meters. In

addition, it shows the trainee the proper distribution of building loads.

1.2 Content analysis:

Parallel and Series Connection Of Lighting Circuit.

In this lecture we will explain how to connect two lamps in parallel and series and

explain how to measure the current, voltage and resistance. Also, we will indicate

the relationship between temperature and resistance. We will focus also in this

practical lesson on safety and standards of electrical installation.

Department: EP- 6

Topic: Parallel and Series Connection Of

Lighting Circuit.

AVP-2 – Lesson Preparation

1.3 Didactic analysis:

We will start our lecture by asking the trainees what they know about our

topic, then we will explain to them about the connection of lamps in series and

parallel. After that we will make together two panels , one for parallel

connection and the other for series connection. Then we will explain to them

how to measure the current, voltage and resistance.

2.1 Objectives

General Objectives:

The Trainees:

Interact with the teacher if he asks questions.

(general – effective - reproduction ).

Solve the problems and answer the questions in the lesson.

(general - cognitive – reorganization).

The trainee find solution if he find a problem.

(general – cognitive – reorganization).

Specific Learning Objectives:

The Trainees:

connect the circuit of the two lamps in parallel.

Wiring the circuit by using different tools.

measure the voltage of the circuit.

know how to use the ammeter to measure the different functions in the circuit.

2.2 Safety instructions:

The trainee should wear shoes.

The trainee must ask the trainer to check the circuit before switch it on.

3.1 Opening / Entrance / Motivation

Methodology Media

Time

Expected Trainer-action Expected Trainee-action Min

The trainer greets the students and ask them about what did they learn from last lesson.

The trainee discuss with the trainer.

Principle of motivation

PPT #1

30 sec

Trainer introduces his topic by asking the trainees questions about connection of the lamps in the class such as:

What do you think about

type of lamps connection in this class? (series or parallel)

Why is better to use parallel

connection in this class

instead of series connection ?

Trainees listen and discuss with the trainer

about the connection of lamps and sharing

ideas.

Classroom discussion 1

Trainees answer the questions:

o The connection in this class is

parallel.

o Because the voltage always

remains constant and only the

amount of current required by a

device is supplied to a device, and

the voltage in series divided by

loads.

Trainer gives trainees sheet of

circuit drawing, and explains how to

read and understand it.

Trainees understand circuit drawing of lamps.

Sheet Paper & PPT Slide #(16)

30 sec

Trainer divides the trainees to two groups.

- Group A will connect the two lamps in series.

- Group B will connect the two lamps in parallel.

Trainees go into two groups each contain about 5 of them.

Group work Experiment 4 Trainer gives the trainees hand tools

and explains how to use them . Trainees focus and follow the instructions of using hand tools.

Trainer shows to trainees the correct color of cables to use (brown for lines and blue for natural).

Trainees listen to trainer and understand the standers of cables color.

8

Trainer connect with trainees the wires from the terminal blocks to the switches and the lighting depend on the circuit drawing that they have and consider the following:

Suitable length of wires. Tight terminal screws. Strip off the wires at about 1

an inch of insulation from both side.

Remove insulation correctly. Put all wires inside trunking. Leave slack on cable.

Trainees focus ,understand the connection step by step.

Group work Experiment 23

Trainer plug the two circuits in the power supply with trainees to check their work.

Trainer know clearly how they can connect the circuits to the power supply.

Trainer measures with trainees:

𝑉𝑆 , 𝑉1 , 𝑉2 𝐼𝑆 , 𝐼1 , 𝐼2 Resistance of lamps in series

and parallel.

And order of them to write the measurements values down in measurement paper.

Trainees understand how to measure all the values of parallel and series circuits and they write the values down.

Trainer explains how to measure

temperature of the lamps in series

and parallel circuits and indicate the

relationship between temperature

and resistance through the curve.

Trainees understand and know what is the relationship between temperature and resistance in series and parallel circuits.

3.3 Close (Reflection, Feedback)

Methodology Media

Time

Expected Trainer-action Expected Trainee-action Min

Trainer make a quick summary by asking the trainees these questions: 1) What kind of circuit is more

commonly used?

2) Why use parallel circuit in the

household lighting?

3) Which type of lighting circuit

connection has voltage is divided

equally between the lamps?

4) What is the name for a circuit

that has only one path for current

to flow?

5) What happens to the lights in a

series circuit if one light goes off?

And why?

6) What happens when one light

goes out in a parallel circuit?

Trainees answer the questions: 1) Parallel circuit.

2) If one bulb is damaged or

switched off, the other bulb can

still work.

3) Series circuit.

4) Series circuit.

5) All the lights go off. Because of

the gap. There is no other path

for the current.

6) The other lights can stay on.
