Circuitry Constructions Aim: To practise creating the electrical circuits that will be implemented into our house Keywords: Electrical circuit, components, motor, light, wire This lesson we attempted to construct the electrical circuit that will be implemented into our house, with the school electrical supplies, so that when it comes time to insert our circuit into the house, we will know how to connect all of the components, how much wire we will need and where each component will go. First of all, the components that we are using, as I mentioned in last lesson’s post, are four light bulbs, one motor, five switches, 1.5m of wire and a power source. We will be supplied with two light bulbs, however the other two lights will be LEDs. The LEDs that we have are only 3V and the transformer that is supplied increases by 2V starting at two. This means that going above 2V could blow the LEDs, but staying at 2 will mean that the LED won’t have the required energy to work properly. In order to fix this, we will not be using the transformer, but rather a battery with a 3V battery or two 1.5V batteries. The circuit that will be implemented into our house is a parallel circuit with 5 branches each with its own switch, 4 connected to a light bulb/LED and the 5th is connected to the motor. This is illustrated on the diagram below. ![]() The intended positioning of our electrical components overlaid onto our house ![]() A working example of the circuit that we are going to implement into our house. Lesson Summary:
Constructed a mock circuit according to the floorplan of the house Considered and decided on the electrical components that will be required Practised constructing circuits according to a corresponding electrical diagram.
