Technology Education Centre 05. Aims: To provide opportunities for improving skills in using the Livewire ‘Electronics’ software. And to promote a better understanding of electronics Systems. ( Live Wire, Control Studio and PCB Wizard)

Technology Education Centre 05. Objectives: To introduce teachers to Live Wire, Control Studio and PCB Wizard 3 software To explore and develop the ‘Live Wire’ software in relation to school based projects and electronic circuit design for Key Stage 3 & 4 To experience all three software packages in the design and construction of Circuit design and the construction of PCB’s To develop strategies for teaching this new software at Key Stage 3 and 4 ( Live Wire, Control Studio and PCB Wizard)

Technology Education Centre 05. Livewire is a simulated electronics laboratory that uses animation and sound to demonstrate the principles of electronic circuits. Switches, transistors, diodes, integrated circuits and hundreds of other components can all be connected together to investigate hidden concepts such as voltage, current and charge. There are no limits to the circuits that can be designed and no loose connections or faulty components to worry about. However, if the maximum ratings for any components are exceeded, they will explode! Technology Education Centre 05.

Technology Education Centre 05. Capacitors Radial electrolytic capacitor Capacitors: A Capacitor stores electric charge. It consists of two plates separated by an insulator called the dielectric. The charge stored depends on the size of the capacitor and the voltage applied to it. The unit of capacitance, the farad, is very large and most capacitors you will use are likely to be measured in microfarads (  F) and nanofarads (nF). Polyester film capacitor Ceramic disc capacitor Axial electrolytic capacitor Technology Education Centre 05.

When the switch is closed, a current flows into the capacitor until it is full. If R is a resistor with a high resistance the current flows slowly, and if it is a resistor of low value the current flows quickly. Compare this with water from a tap filling a basin. The amount of water flowing into the basin is altered depending on whether the tap is fully open or almost closed.

Technology Education Centre 05. Ex 11 (b): Capacitors Build the circuit as shown press and hold SW1 and test how long it takes for the voltage meter to reach 9V using:- a)R1 = 1K b)R1 = 10K c)R1 = 100K Time constant (sec) = C (farads) X R (ohms)

Technology Education Centre 05. Time Constant When the switch is closed and the capacitor starts to charge, the voltage output can be monitored using a voltmeter. To start with the voltmeter will show 0V, increasing to 9V when the capacitor is fully charged. A graph can be plotted of the voltage output against the time taken. Time constant (sec) = C (farads) X R (ohms) The first part of the graph is almost a straight line, which then curves and tails off as it takes longer and longer to fill the capacitor. The time taken to reach two thirds of the supply voltage is called the time constant and can be calculated using the formula: Technology Education Centre 05.

Transistors are semiconductor devices. This means that they have a resistance to the flow of electrons – current. However they become conductors if a small voltage is provided across two of the legs – the base and the emitter. Collector (c) Emitter (e) Base (b) Symbol for the n-p-n transistor You can use the transistor as a high speed switch if a small voltage of 0.6 – 1.6V is applied to the base leg as shown below The Transistor Technology Education Centre 05.

Technology Education Centre 05. In the light the voltage between the base and the emitter leg of the transistor is 657mV or 0.65V. For this transistor the voltage is not enough to switch it on – therefore the bulb remains off. In the darkness the voltage between the base and the emitter leg of the transistor is 739mV or 0.739V. This voltage is high enough to switch on the transistor – therefore the bulb is switched on.
