Solar Power
In the section “Energy in the Environment” pupils are expected to be familiar with the renewable energy sources that are available to us. This model illustrates clearly the possibility of harnessing electrical power from the sun.
Reverse Drive for Electric Motor
Used in conjunction with the Nuffield Operational Amplifier this rather complicated circuit is set out in a manner which clearly demonstrates the use of transistors in producing forward and reverse drive for an electric motor.
Mounted Motor
The motor is a 1.5V medium torque motor which can be worked over the range 1.0 – 6.0 V and as such can be run off a 1.5V cell. It is therefore ideal for the primary schools where low voltage power packs may not be available.
Solar Power
The 1000 mA solar cell placed in brigth sunlight or 10 cm fron a 36 W bulb or a 60 W mains bulb can be used to drive the motor.
