Series and Parallel Connection Of Bulbs and Socket Outlets

CLASS WORK PROJECT

 

CONNECTION SERIES AND PARALLEL OF BULBS AND SOCKET OUTLETS

 

Introduction

The project is showing 2-lamps in parallel controlled switch, by 2-way switches with intermediate switch, 1-gang, 1-way switch controlling two series connected lamps, single and double socket outlets connected in parallel and single and double socket outlets connected in series.

The project was to test the lighting of bulbs connected in series and the parallel and voltage of socket outlets connected in parallel and in series .

Objectives

•  To compare the advantages and disadvantages of series over parallel circuit.
• To demonstrate the operation of two way switches with intermediate switch
• To equip students with the knowledge of wiring two different wiring system i.e. series and parallel

Challenges

• There was a problem of lack of enough money to buy all the components
• Difficulties in designing the circuit diagram since only a list of materials was given

Tools used 

• Pliers: This was used to hold cables as well as peeling off insulators on cables
• Hammer: This was used to fix nails into the board  
• Tester: This was used to test the presence of current in a circuit 
• Screw driver(flat and star): This was used to loosen and tighten knots

Materials used

• Bulbs
• Lamp holders 
• Junction boxes 
• Socket outlets 
• Switches Cables 
• Clips and nails 
• Intermediate switch 
• Power cable

Safety precautions

•  One should always observe insulation of tools to avoid electric shock
• Power must be switched off whenever an equipment is being assembled 
• Do not work alone while working with high voltage electric equipments
• Chairs and stools should be under the benches when not in use 
• Wearing a ring or watch can be hazardous in an electric lab since such items make good electrodes for the human body
• Never touch electrical equipment while standing on a damp or metal floor

Procedure
The main switch was placed in its position and the power cable connected to it
 

The testing of current was done by use of a tester and then plugged out of the power supply
 

Junction boxes were fixed in their rightful position with two on either sides of the main switch and the cables of 1.5mm and 2.5mm were connected to the switches, lamp holders and socket outlets respectively from and in the junction boxes
 

To the right, a single socket outlet and a double outlet were connected to one junction box in parallel and another single socket outlet and double socket outlet were connected to the second junction box in series
 

To the left, one junction box was connected to lamp holders in series with 1gang switch and their circuit closed. Another junction box was connected to lamp holders in parallel and two 2-way switches with an intermediate switch in between them
 

Conclusion 
All the bulbs light but with two bulbs in series blinking
When the intermediate switch is turned off, the 2-way switches do not function or do any task and the bulbs in parallel do not light
The 1gang switch controls both bulbs in series since current flows along only in one path
